Here at St Martin Metal, we design and sell steel buildings of all different shapes and sizes. Whether you're looking for an engineered, rigid I-beam frame, or maybe a simple component-style construction, we've got it right here. We also offer fiberglass insulation, windows, entry doors, roll-up doors, and more. Already have a steel building or covered patio and want to add on to it, or close it in? No problem. We can supply every component you would need, pre-cut to specific lengths. Our red oxide and galvanized structural components can be pre-punched with bolt holes to make installation a breeze. We offer many structural components such as Open Channels, Cees & Zees, Base Angles, Eave Struts, and more, ranging from 4", 6", 8", 10" & 12" Web sizes, from 12-16 gauge. We also offer galvalume and painted panels ranging from 22-29 gauges, for roofing and wall sheets.
