IMPORTANT: Recommended Installation Procedures
It is important that the cleats are installed properly to secure your cables:
• It is not necessary for every cleat to be attached to the ladder. Every other cleat ( ) must be
attached to the ladder system to secure cable. Unattached cleats ( ) provide additional restraint
to keep cables bundled.
• The bend radius should be 8 to 12 times the cable diameter.
• Cable cleats should always be installed at the beginning, middle and end of a bend ( ), and at
no time should the distance between cleats on a bend be more than 0.3M center to center.

Strut Systems - Technical Data
MATERIALS
Carbon Steel
Channels made from high-quality carbon steel are continuously roll formed to precise dimensions. By cold working the steel
mechanical properties are increased, allowing lightweight structures to carry the required load. Corrosion resistance of carbon
steel varies widely with coating and alloy. See “Finishes” for more detailed information.
Stainless Steel
Stainless steel channel is available in AISI Type 316 material. Type 316 is non-magnetic and belongs to the austenitic stainless
steels group, based on alloy content and crystallographic structure. Like carbon steel, stainless steel exhibits increased strength
when cold worked by roll-forming.
Several conditions make the use of stainless steel ideal. These include reducing long term maintenance costs, high ambient
temperatures, appearance, and stable structural properties such as yield strength, and high creep strength.
Type 316 resists most organic chemicals, dye stuffs and a wide variety of inorganic chemicals at elevated or cryogenic
temperatures. Type 316 contains nickel and molybdenum to give it better corrosion resistance in chloride and sulfuric acid
environments. More specific information concerning Type 316 is available from B-Line.

FINISHES
Zinc Coatings
Zinc protects steel in two ways. First it protects the steel as a coating and second as a sacrificial anode to repair bare
areas such as cut edges, scratches, and gouges. The corrosion protection of zinc is directly related to its thickness and the
environment. This means a 5µm coating will last twice as long as a 2.5µm coating in the same environment.
Galvanizing also protects cut and drilled edges.
Electrogalvanized Zinc
Electrogalvanized Zinc (also known as zinc plated or electroplated) is the process by which a coating of zinc is deposited on
the steel by electrolysis from a bath of zinc salts.
A rating of Fe/ZN 5 also known as SC1, B-Line hardware standard, provides a minimum zinc coating thickness of 5µm.
When exposed to air and moisture, zinc forms a tough, adherent, protective film consisting of a mixture of zinc oxides,
hydroxides, and carbonates. This film is in itself a barrier coating which slows subsequent corrosive attack on the zinc.
This coating is usually recommended for indoor use in relatively dry areas, as it provides ninety-six hours protection in salt
spray testing per AS 2331.3.1 / ASTM B117.

WELDING
The welding procedures used in the fabrication of B-Line steel products are in accordance with recognized industry standards.
To achieve the highest quality in our manufacturing processes, our welders are 3rd party certified.
MIG Welding
MIG welded, more properly called gas metal arc welded (GMAW) combination channels and fittings, are produced when
physical dimensions or certain combinations require a weld process other than automatic spot welding. The same quality
control requirements are imposed on MIG welded and spot welded products.
Quality Assurance
Our Quality Assurance Program has been developed and implemented for
compliance with ISO 9001:2008. B-Line also complies with various industry
standards and specifications.

Hot Dip Galvanized After Fabrication (Hot dip galvanized or batch hot dip galvanized)
Hot dip galvanized strut products are fabricated from steel and then completely immersed in a bath of molten zinc. A metallic
bond occurs resulting in a zinc coating that completely coats all surfaces, including edges and welds.
Another advantage of this method is coating thickness. Strut products that are hot dip galvanized after fabrication have a
minimum thickness of 460g/m2 on each side, or a total 920g/m2
, according to AS/NZS 4680 / ASTM A123.
The zinc thickness is controlled by the amount of time each part is immersed in the molten zinc bath as well as the speed at
which it is removed. The term \"double dipping\" refers to parts too large to fit into the galvanizing kettle; therefore, must be
dipped one end at a time. It does not refer to extra coating thickness.
The layer of zinc which bonds to steel provides a dual protection against corrosion. It protects first as an overall barrier
coating. If this coating happens to be scratched or gouged, zinc's secondary defense is called upon to protect the steel by
galvanic action.
Hot-Dip Galvanized After Fabrication is recommended for prolonged outdoor exposure and will usually protect steel for
20 years or more in most atmospheric environments and in many industrial environments. For best results, a zinc rich paint
(available from B-Line) should be applied to field cuts. The zinc rich paint will provide immediate protection for these areas
and eliminate the short time period for galvanic action to “heal” the damaged coating.

CORROSION
All metal surfaces are affected by
corrosion. Depending on the physical
properties of the metal and the
environment to which it is exposed,
chemical or electromechanical corrosion
may occur.
Atmospheric Corrosion
Atmospheric corrosion occurs when
metal is exposed to airborne liquids,
solids or gases. Some sources of
atmospheric corrosion are moisture, salt,
dirt and sulphuric acid. This form of
corrosion is typically more severe
outdoors, especially near marine
environments.
Chemical Corrosion
Chemical corrosion takes place when
metal comes in direct contact with a
corrosive solution. Some factors which
affect the severity of chemical corrosion
include: chemical concentration level,
duration of contact, frequency of
washing, and operating temperature.
Storage Corrosion
Wet storage stain (white rust) is caused
by the entrapment of moisture between
surfaces of closely packed and poorly
ventilated material for an extended
period. Wet storage stain is usually
superficial, having no affect on the
properties of the metal.
Light staining normally disappears with
weathering. Medium to heavy build up
should be removed in order to allow the
formation of normal protective film.
Proper handling and storage will help to
assure stain-free material. If product
arrives wet, it should be unpacked and
dried before storage. Dry material should
be stored in a well ventilated “low
moisture” environment to avoid
condensation formation. Outdoor storage
is undesirable, and should be avoided
whenever possible.

Galvanic Corrosion
Galvanic corrosion occurs when two or more dissimilar metals are in contact in the presence of an electrolyte (ie. moisture). An
electrolytic cell is created and the metals form an anode or a cathode depending on their relative position on the Galvanic Series
Table. The anodic material will be the one to corrode. Anodic or cathodic characteristics of two dissimilar metals will depend on
the type of each material. For example: If zinc and steel are in contact, the zinc acts as the anode and will corrode; the steel acts
as the cathode, and will be protected. If steel and copper are in contact, the steel is now the anode and will corrode.
The rate at which galvanic corrosion occurs depends on several factors:
1. The relative position on the Galvanic Series Table - the further apart materials are in the Galvanic Series Table, the greater the
potential for corrosion of the anodic material.
2. The amount and concentration of electrolyte present - an indoor, dry environment will have little or no galvanic corrosion
compared to a wet atmosphere.
3. The relative size of the materials - a small amount of anodic material in contact with a large cathodic material will result in
greater corrosion. Likewise, a large anode in contact with a small cathode will decrease the rate of attack.

Beams
Beams are usually defined as horizontal members which are subjected to vertical loads such as shelves, platforms or supports
for pipes, conduits or cable ladders. The following is a brief overview of common beam configurations:
Simple Beam
An example of a simple beam is a length of channel placed across two cylinders. When a load is
applied, the channel will support the load because of its stiffness. The cylinders serve to support
the channel, but do not interfere with its natural tendency to flex or bend. Simple beam analysis is
used almost universally for beam comparisons, even though it is seldom practical in field installations.
A cable ladder or conduit trapeze hanger closely resembles a simple beam.
Fixed Beam
This type of fixed support restricts the movement of the ends of the channel when a load is applied.
Because of this, the stiffness of the channel at the ends and center is employed to resist the load.
The result is a load capability which is greater than that of an identical simple beam.
The fixed beam can be approximated by bolting or welding a length of channel to rigid supports.
Cantilever Beam
Cantilever beams are often viewed as variations of a fixed beam, but they have special characteristics
of their own. One end of the channel is firmly attached to a rigid support while the other end remains
completely free.
A shelf bracket is an example of a cantilever beam.
Continuous Beam
This beam configuration is commonly used in lighting installations. The continuous beam
possesses traits of both the simple and fixed beams. When equal loads are applied to all
spans simultaneously, the counter-balancing effect of the loads on both sides of a support
restricts the movement of the channel at the support, similar to that of the fixed beam. The
end spans behave substantially like simple beams.
Continuous beam installations can typically support 20% more load than a simple beam of
the same span with approximately half the deflection.
Therefore, simple beam data should be used for a general comparison only. An example of this configuration is found in a long run of
channel when installed across several supports to form a number of spans.
Deflection
Deflection, commonly referred to as “sag”, is inherent in applying a load to a beam and cannot be avoided.
Any and all beams will deflect when loaded. The amount of deflection will vary depending upon the material
and the stiffness or moment of inertia. The deflection equations in this section show that increasing the
stiffness can be increased by a variety of methods. Increasing the depth of the channel is the most direct
method.
The material used affects deflection in a manner which is significantly different from the way in which it affects load capacity. The
deflection under load is inversely proportional to a material property known as the “modulus of elasticity” designated by “E”.
The modulus of elasticity is dependent upon the basic composition of the material and is not necessarily related to the material’s
strength.
Safety Factor
The design loads given for strut beam loads are based on a simple beam condition using allowable stress of 172 MPa. This allowable
stress results in a safety factor of 1.68. This is based upon a virgin steel minimum yield strength of 227 MPa cold worked during rolling
to an average yield stress of 289 MPa.
Aluminum typically has an elastic modulus which is 1/3 that of steel even though they may have identical strength. As a result, the
deflection of aluminum channel will be three times that of steel channel under equal loading. In areas where structures will be subject
to general viewing, deflection can produce a displeasing effect. To the untrained eye, a sagging channel may appear to be a result
of poor design or excessive loading. This is not usually the case. Many properly designed channel installations will show a noticeable
deflection at their designed loads. In areas where cosmetics are not important, deflection should not be a factor. Designing an entire
installation based on minimal deflection could result in an over designed structure. This translates into increased material and
installation cost. Where cosmetics are important, it may be necessary to limit the deflection to an aesthetically pleasing amount. This
“acceptable deflection” amount is typically given as a fraction of the span. 1/240 span deflection is typically the limit where the
amount of deflection appears negligible. For example, a beam span of 6000mm would be allowed 25mm (6000/240) of deflection at
the mid point. A 3000mm span would only be allowed 12.5mm (3000/240) of deflection. The maximum load for the channel must be
limited in order to remain under these deflection requirements. The allowable load resulting in 1/240 span deflection is posted in the
beam load chart for each channel size.
For even more stringent deflection requirements, an allowable load is listed in the beam load charts which results in 1/360 span
deflection. This amount of deflection is sometimes used for beams in finished ceilings that are to be plastered.

Twisting & Lateral Bracing
Loading of strut on long spans can cause torsional stress, resulting in the tendency of the strut to twist or bend laterally. This
phenomenon reduces the allowable beam loads as shown in the beam loading charts. It is recommended that long spans be
supported in a manner to prevent twisting (fixed ends), and that the channel have adequate lateral bracing. Many typical strut
applications provide this support and bracing inherently. Piping, tubing, cable ladders, or conduits mounted to the strut with
straps and clamps prevent twisting or lateral movement. If no such lateral support exists, contact the factory for loading
recommendations.
Columns
Columns are vertical members which carry loads in compression. One common example of a channel column is the vertical
members of a storage rack.
In theory, a column will carry a load equal to its cross sectional area multiplied by the ultimate compressive stress of the material
of which the column is made. In reality, there are many factors affecting the load capacity of a column, such as the tendency to
buckle or twist laterally (torsional-flexural buckling), the type of connection at the top or bottom, the eccentricity of the load
application, and material imperfections. Several of these failure modes have been considered in the allowable column load tables
shown in the “Channel” section of this catalog.
B-Line strongly recommends that the engineer perform a detailed study of the many variable conditions before the selection
process begins.
Design Factors to be Considered
The loading capacity of channel depends primarily on the material, its cross-sectional design, and the beam or column loading
configuration. It should be noted that if two lengths of channel have identical designs and configurations, the one made of the
stronger base material will support a larger load. Therefore, any comparison of channel should begin by determining whether the
materials are approximately equal in strength.
The column loading chart for each channel lists the allowable load for each channel in compression. This load varies depending on
the support condition or “K-factor”.
Several “K-factors” are listed, which correspond to the following support conditions:
K = .8 pinned top - fixed bottom
K = .65 fixed top - fixed bottom
K = 1.0 pinned top - pinned bottom
K = 1.2 free top - fixed bottom
There are a number of physical properties which are important to the complete design of a channel member; the “section
modulus” designated as “Sx” or “Sy”, “moment of inertia” designated by “Ix” or “Iy”, and the “radius of gyration” which is given
as “rx” or “ry”.
Every structural material has its own maximum or ultimate stress, which is usually expressed in pascals. Any load which causes
a member to fail is referred to as its “ultimate” load. In order to prevent channel from being accidentally loaded up to or beyond
its ultimate load, a safety factor is included into the design. The ultimate load is divided by the safety factor to obtain the
“recommended” or “allowable” working load.
When evaluating channel under various beam conditions, it is often more convenient to compare in terms of the ultimate or
recommended “bending moment”. Simple equations show the stress is directly proportional to the bending moment.
Therefore, comparing bending moments can save time in repeated calculations. The chart containing Formulas on Common Beam
Loadings (following page) shows how to calculate the bending moment for various configurations and load conditions. It should be
noted that the bending moment is usually not constant, but varies along the length of the span. However, the channel must be
designed for a single point, which is the point of maximum bending moment.

General Information
Torque
The torque values given throughout the catalog are to be used as a guide only. The relationship between the applied torque or
torque wrench reading and the actual tension created in the bolt may be substantially different. For example, a dry non-lubricated
bolt with a heavy plating may rate 50% as efficient as a bolt which is lubricated with a mixture of heavy oil and graphite. Other
important factors affecting torque-tension relationships include friction under the bolt head or nut, hole tolerances, and torque
wrench tolerances. Accuracy of many commercial torque wrenches may vary as much as plus or minus 25%.
Charts and Tables
Charts and tables in this section are compiled from information published by nationally recognized organizations and are intended
for use as a guide only. B-Line recommends that users of this information determine the validity of such information as applied to
their own application.
