Steel Beams VS Aluminium Beams
Aluminum shoring beams represent the highest standard of corrosion resistance.
Compare to the steel structure I beam, the aluminum beams are able to be applied in all weather and water conditions without rust.
6061 T6 aluminum beam is a marine grade alloy material that keeps the aluminum beams in high strength and no corrosion even exposed in wet.
Considering the weight per ft, the aluminum beam is lightweight construction material. Steel structural beams include I beams, H beams, steel angles, steel channels, etc. All of them are of a heavier weight. Thus using aluminum beams is much easier handling and transportation in construction concrete form.
For anti-corrosion, steel beams are always in painting or galvanizing finishing. Because black(self-finished) steel beams rust much easier.
Aluminum beams are with radius corners. It is able to be extruded into different shapes from the alloy ingot. While steel structure beams are fewer choices in shapes.
Aluma Beam Clips
Aluma beam clips are also called A clamps. It is used to fix aluminum beams to beams, stringers, strongbacks, joists, etc.
6.5″ aluminum beams are formulated with a bolt slot at the base. Th slot leaves a space for the aluma A clamps.
The aluma A clamps are made from steel with galvanizing finishing.
