Product Description

Product Description

Steel Structure Solutions — Steel Building, Steel Workshop & Prefabricated House

We supply professional steel structure solutions for industrial, commercial and residential projects, including steel structure building, steel structure workshop, steel structure warehouse, and prefabricated house systems. Our steel construction products combine high-strength structural materials, precision factory fabrication and flexible modular design to deliver durable, cost-effective and fast-to-install buildings. Ideal for applications from light-use temporary housing and mobile offices to heavy-duty industrial workshops and large-span commercial spaces, our offerings cover the full spectrum of steel frame construction.

We combine experienced structural engineering, scalable factory production and end-to-end project support to deliver steel construction solutions that are reliable, economical and easy to deploy — from single steel warehouse units to multi-building modular prefabricated house communities.

Key Features & Benefits

Durable construction using high-strength structural steel (H/I-beams, C/Z purlins, welded box sections) for superior load-bearing performance.
Fast modular fabrication: factory-made panels and modules for prefab house, modular prefabricated house, or on-site assembly for large steel buildings.
Versatile finishes: galvanised steel frame, anti-corrosion coatings, fire-retardant and insulated sandwich panels for thermal efficiency.
Cost-effective & time-saving: reduced on-site labor, shortened construction cycles for steel structure workshop and steel structure warehouse projects.
Mobility & flexibility: options for mobile house, modular housing blocks, and expandable layouts.
Customizable: spans, bay spacing, cladding, doors, windows, mezzanines and internal fit-outs to meet specific project needs.

Light Steel Structure 

Heavy Steel Structure 

Large-Span Space

cold-formed steel sections and light-gauge frames for low-rise buildings and modular prefab units;  ideal for quick, low-cost construction.

hot-rolled H/I-beams, welded connections and plate girders for high-rise, heavy-load industrial buildings and long-life constructions.

trusses, space frames and portal frames engineered for wide-span roofs (sports halls, hangars, exhibition centers) providing column-free interior space.

Technical & Service Options

— Design & engineering (load calculations, seismic/wind criteria), fabrication, surface treatment (hot-dip galvanizing, paint), delivery and on-site installation.
— Compatible with international standards; quality control, material test reports and inspection available.

— OEM/ODM and custom project capacity: modular unit sizing (20ft/40ft container-style modules or bespoke dimensions), accessory supply (doors, windows, insulation, electrical & plumbing fit-out).
