Product Description

Large Span Prefab Steel Building Overview

Pre-engineered steel structure buildings utilize high-strength steel as the primary load-bearing material, forming stable structural systems through welding and bolting connections. These buildings offer exceptional strength-to-weight ratios and modular construction benefits for industrial and commercial applications.

Structural Components & Materials

Primary Load-Bearing Frame

Columns: Q235B (ASTM A36, S235JR), Q355B welded or hot-rolled H-section steel
Beams: Q235B, Q355B (ASTM 572, S355JR) welded or hot-rolled H-section steel
Connection Methods: Welding or high-strength bolted connections

Secondary Structural Elements

Purlins: Q235B, C and Z type steel
Knee Braces: Q235B, angle steel
Tie Tubes: Q235B, circular steel pipe
Bracing: Q235B, angle steel, round bar or steel pipe

Key Performance Advantages

High Strength-to-Weight Ratio: Approximately 50% lighter than concrete structures, reducing foundation costs
Rapid Construction: 30-50% shorter construction periods through factory prefabrication
Large Span Capability: Spans exceeding 30 meters with minimal internal columns
Enhanced Space Utilization: Approximately 4% more usable space compared to traditional structures
Sustainable Construction: 100% recyclable materials with minimal construction waste

Building Enclosure Options

Component	Material Options
Roof & Wall Panels	Metal sheet (PE+Galvanized+Aluminium), Sandwich Panel, Glass wool
Doors	Rolling Up/Shutter Door, Sandwich Panel Door, Stainless Steel Door, Fireproof Door
