Tubular steel members, (ASTM-A500 Grade B), are continuously welded together, fabricating the strongest superstructure, therefore the safest building. For example, horizontal and vertical tube steel structural members, like the horizontal 4″ x 4″ roof tubes, coming together at right angle and connecting on top of the 2″ x 4″ corner wall tube have 20″ of continuous weld! Remember, 1/4″ thick steel has, by weight, 186% more steel than 10 gauge, which has 281% more steel than 18 gauge. Imagine how much weaker buildings with 20 gauge common steel studs in walls are as compared to 1/4″ thick tubular steel vertical members. With walls from 3/16″ up to 5/8″ thick.
Here’s the difference: A steel worker picks up off the shop floor a single eight foot long section of common 4″ steel wall stud. The stud is grabbed at one end and the worker can literally shake it so that it wiggles along its length. But Haz-Safe’s smallest member, a 2″ x 2″ (3/16″ thick wall) tube, has to be picked up differently. The tube is handled in the middle of its length because it is too heavy to be picked up from one end and is solid with no wiggle. So, when hundreds of tubes are continuously welded into a skeleton, the resulting building doesn’t wiggle or bend either (see photos below).
