Q235 / Q355 Steel Structure Warehouse

Q235 / Q355 Industrial Galvanized Metal Prefabricated Frame Workshop & Warehouse Steel Structure with Gable Frame

Q235 / Q355 Industrial Galvanized Metal Prefabricated Frame Workshop & Warehouse Steel Structure with Gable Frame When global buyers search for a reliable prefabricated steel structure warehouse, two priorities consistently lead every project conversation: structural grade and surface protection. This product addresses both directly — delivering a gable frame steel structure engineered from Q235B and Q355 steel, with full hot-dip galvanization across every primary member, secondary purlin, and connection node.

What Is This Steel Structure Warehouse?

This is a factory-fabricated, bolt-assembled industrial building solution designed for warehousing, manufacturing workshops, distribution centers, and logistics facilities. The load-bearing frame uses a classic portal gable frame configuration — combining tapered or straight H-section columns and roof beams to eliminate interior columns and maximize usable floor space.
The structural steel grade is selectable between Q235B (yield strength ≥ 235 MPa, equivalent to ASTM A36) and Q355 (yield strength ≥ 355 MPa, equivalent to ASTM A572 Grade 50). Both conform to GB/T 700 and GB/T 1591 standards.

Why Galvanization Matters for Industrial Warehouse Structures

Hot-dip galvanization creates a zinc-iron alloy layer protecting steel surfaces at ~450°C, ensuring long-term corrosion resistance.
Key performance indicators:
  • Zinc coating thickness: 80–120 g/m² (up to 150 g/m² optional)

  • Salt spray resistance: 1,000+ hours

  • Service life: 25–50 years

Structural System and Design Parameters

Gable frame portal structure provides clear-span space and efficient drainage.
  • Span: 9–60 m+

  • Bay spacing: 6 m / 7.5 m / 9 m

  • Eave height: 4.5–14 m

  • Wind load: up to 0.5 kN/m²

  • Roof live load: 0.3–0.5 kN/m²

  • Connection: high-strength bolt system

Material Components — What Is Included in Each Kit

  • Primary frame: H-section steel columns and beams

  • Secondary structure: C/Z purlins and girts

  • Bracing system: cross bracing, tie rods

  • Cladding: steel sheet or sandwich panels

  • Accessories: gutters, flashing, bolts

  • Doors & windows: sliding / rolling / skylights

Frequently Asked Questions

Q: What is the difference between Q235B and Q355?

Q235B is standard structural steel, Q355 has higher strength and is used for heavy loads or large spans.

Q: Why use hot-dip galvanization?

It provides 25–50 years corrosion protection without repainting.

Q: What is the production lead time?

Typically 30–45 days after drawing confirmation.

Q: Can the structure be expanded?

Yes, modular design allows future extension.

Q: Do you provide inspection reports?

Yes, including material certificates, QC reports, and third-party inspection options.
