Steel Building Systems

Steel is the cost-effective and environmental friendly alternative to any other construction materials because, since the structures are usually constructed much faster than using other materials the costs are usually lower compared to traditional building methods. Lighter weights, easiness in maintenance, reduced risk of fire and 66% recyclability of steel has increased the benefits of it. Above all, strength is a major plus for steel. Steel structures can withstand unfavorable weather conditions such as hurricanes, high winds, heavy snow, tsunami and even earthquakes. They are also resistant to termites, creeping, cracks, splitting and rotting, thus increasing durability.

Steel construction is becoming most popular nowadays. And first time in Sri Lanka “RMI STEEL BUILDING SYSTEMS” is delivering locally manufactured all steel building components under one roof such as pre fabricated steel structures, pre engineered steel structures, Zinc Aluminum roofing products, heat insulation products and ventilation systems.
