THE PROBLEM

Every warehouse
Every grocery store
Every building you walk into
Held up by crimped angle iron

The SJI standard joist has been the default specification for decades. Thin crimped angle iron. Eccentric (out of centerline) connections. Re-certified A36 steel. Built to the minimum. Accepted without question. Until the roof comes down.

SJI STANDARD JOIST

Crimped angle iron. Eccentric load path. Re-cert A36. This is what is holding up your roof right now.

THE SOLUTION

Safer. Faster.
Longer. Stronger.

Dual HSS square tube. Mirrored geometry. Pure axial loading. No eccentricity. No re-cert A36 penalty. Laser welded connections that preserve the steel. L/480 standard — twice the code minimum. 55% fewer members per bay.
