Custom Designed Steel Structure Building with 50 Years Lifespan and 8 Grade Earthquake Resistance

Steel is the most important building material in the world because of its light weight and high strength. Steel has the highest strength-to-weight ratio of all building materials, meaning that its members add strength without adding stress to the building frame.

This advantage gives our engineering team more flexibility when designing structures. The steel buildings can be easily modified in layout and designed with clear spans to meet larger space requirements. Another major benefit is lower cost and less waste compared to traditional building materials. Larger buildings yield greater cost savings, with reduced steel prices and smaller groundwork requirements. As an environmentally friendly material, steel produces almost no waste and can reduce energy costs over time.

The main components of steel structure buildings:

• Primary Framing: Main steel frame composed of steel beams, columns, and trusses made from section steel and steel plate, with rust removal and anti-rust processes like shot blasting, painting, and galvanizing. Connections use welding, bolts, or rivets.
• Secondary Framing: Includes bracing, Z and C section purlins that connect the main frame and help resist longitudinal loads like wind and earthquakes. Purlins come in 1.8mm to 3.0mm thickness with galvanized sheets.
• Roof and Wall Cladding: Steel sheets with galvanized or aluminum-zinc base and organic coating for corrosion resistance. Also available as sandwich panels with insulated core materials (EPS, fiberglass, rock wool, or PU) in thicknesses from 50mm to 200mm.

• Fully customizable size and layout
• Large clear spans up to 70m without middle columns
• Environmentally friendly with minimal waste and foundation requirements
• Customizable doors, windows, and interior partitions
• Aesthetic appearance with various color options
• Cost-effective with convenient transportation
• Quick installation and easy maintenance
• Anti-rust treatment with 50+ year lifespan (paint or hot-dip galvanization)
• Stable structure resistant to 8-grade earthquakes
• Engineered to withstand local snow, wind, and live loads

Our team designs cost-effective building systems for various applications:

• Industrial Buildings
