50 Years Life Cycle Pre-engineered Steel Structure with Quick Erection and Cost Savings

Prefabricated Steel Structure Building with Economical Design

Pre-engineered steel buildings are steel structures built over a structural concept of primary members, secondary members, roof and wall sheeting connected to each other and various other building components.

These buildings can be provided with different structural and non-structural additions such as skylights, wall lights, turbo vents, ridge ventilators, louvers, roof monitors, doors & windows, trusses, mezzanine floors, fascias, canopies, crane systems, insulation, etc., based on customer requirements. All steel buildings are custom designed to be lighter in weight and high in strength.

• Factories
• Workshops
• Warehouses
• Cold Storages
• Steel Mills
• Assembly Plants

• Showrooms
• Supermarkets
• Offices
• Shopping Centers
• Exhibition Halls
• Restaurants

• Schools & Hospitals
• Conference Halls
• Laboratories
• Museums & Stadiums
• Farms
• Aircraft Hangars

Price per square meter can be 25%-30% lower than conventional steel buildings. Site erection cost is low due to faster erection times and easier installation process.

All steel components are fabricated at the factory and linked by bolts at the site. Erection process is fast, step by step, easy to install and requires simple equipment. 60% less construction time required compared with traditional R.C.C. buildings.

Pre-engineered steel buildings are flexible in design requirements, easy to expand in the future, and economical with low transportation costs.

Pre-engineered buildings are environmentally friendly with CO2 reduction, energy efficiency, and recyclability.

• Primary Members / Main Frames - Main load carrying and support members including columns, rafters
• Secondary Members / Cold Formed Members - Purlins, girts, eave struts, wind bracing
• Roof & Wall Panels - Standard steel panels 0.3-0.6mm thick with protective coatings
• Accessories - Anchor bolts, fasteners, doors, windows, ventilators, insulation
• Sandwich Panels - For enhanced insulation and structural performance
