Xtrong

BSRM XtrongXtrong is a high strength structural steel conforming to ASTM 572 Grade 50 and ISO 630 Grade 345 Channels and Angles section rolled out of this high strength steel provides an economical alternative to steel fabricated structures compared to traditional ASTM A-36 steel. Structures made out of Xtrong or Grade 50 steel requires 18% to 25 % less steel compared to Grade 36 steel.

BSRM makes Angles, conforming to Grade 50 in the following sizes.

Open Web Joist supported concrete floor

APPLICATIONS: One of the promising applications of Grade 50 Angles is in the fabrication of Open Web Joists (OWJ) for supporting concrete floors under profiled steel deck

OWJ supported floor systems is the universally accepted method of constructing floors in even in tall buildings in North America and Europe. Floors supported by OWJ are much lighter and reduces the dead weight of buildings making it lighter and safer.
