Hot Rolled Plates

These are made up of 3 hot rolled plates of equal or varying thicknesses welded together to for an I-Section. Mammut use high grade steel plates conforming to ASTM A572M Grade 345 Type 1 (Minimum Yield Strength is 345 Nmm2). The advantage of using a built-up section as compared to a hot rolled profile section is, these can be profiled into a tapered member to cater for the stress concentration in a building. The flexibility of having different thicknesses for top and bottom flange adds to the advantage and makes built-up sections much economical compared to hot rolled profiles. The built-up sections are factory painted with a minimum of 50 microns (DFT) of red oxide primer as our standard or any other paint system as per customer choice.
