In time past, GATEWAY INDUSTRIES has become aware of instances of sub-standard, inferior aluminum beam sold to the field.
Occasionally, we are asked by what means do we certify our product.
What makes beam members sub-standard? Generally, such beam may flex and take a permanent set (bend) because of inferior alloy chemistry and the lack of conformance to Aluminum
Association alloy and temper specifications. Questionable beam may also lack conformance to dimensional specifications.
How does GATEWAY certify its product?
First, ALL GATEWAY BEAM
conforms to the 6061 Aluminum Association’s alloy specification, T6 tempered. This alloy is specifically used for structural applications requiring a high strength to weight ratio. 6061 has good corrosion resistance and strength similar to A36 steel, and has been the standard for aluminum beam shoring.
 In fact, GATEWAY’s alloy chemistry calls for more silicon than the Association’s
minimal chemical specification in order to guarantee metal on the high side of the 6061 alloy range for mechanical strength.
ACTUAL TEST REPORT...
Each and every production lot of GATEWAY INDUSTRIES beam undergoes inspection, chemical and mechanical testing, with all data on file for
perusal. Chemistry is analyzed with the latest ARL spectrometer techniques, and each lot is tested for tensile strength, yield and elongation (see adjacent
sample report). All internal manufacturing processes conform to the ASTM B221 specification, with full lot traceability. With the proper chemistry, mechanical strength and a variety of
dimensional and regular fitness-for-use testing, each lot is certified for shipment.
There is no way that GATEWAY INDUSTRIES beam will not meet design criteria.
We at GATEWAY INDUSTRIES regret the confusion created in the field by incidences of sub-standard product and wish to confirm and commit our continuing diligence in
creating the industry’s superior aluminum beam products.
Thank You For Your Patronage.
