Prefabricated Steel Frame Workshop Warehouse Steel Structure Building

Superior Anti-corrosion Performance
All steel structural members adopt full hot-dip galvanized surface treatment. The zinc coating forms a stable protective layer, effectively resisting rainwater, humidity, salt fog and chemical erosion, extending the service life of the building up to 50 years without frequent maintenance.
Fast Production & Quick On-site Installation
All components are prefabricated and processed in our factory in strict accordance with construction drawings, including cutting, welding, drilling and galvanizing. Only simple assembly work is required on the construction site, greatly shortening the overall construction period compared with traditional concrete buildings. The first batch of goods can be delivered within 60-70 days after receiving advance payment and confirmed drawings.
High Structural Strength & Stable Load-bearing Capacity
We adopt high-grade steel such as Q355B as raw material. H-beams, channel steel, angle steel, square & rectangular tubes and round steel components are reasonably matched in structural design. The frame features strong seismic resistance, wind resistance and heavy load capacity, which can meet the usage demands of large-span factories, warehouses, exhibition halls and office buildings.
Flexible Customization for Various Scenarios
We support full customization according to customer’s drawings and project demands. Adjustable span, height, load standard, door/window layout and internal partition layout. Widely applicable to industrial workshops, logistics warehouses, commercial exhibition centers, parking lots, farm barns and multi-story steel structure office buildings.
Economical & Cost-effective Solution
Light self-weight of steel frame reduces foundation engineering cost. Prefabricated processing cuts labor cost and construction time. Our quotation is transparent and valid for 5 working days; we will adjust unit price and container loading quantity based on final official drawings to control your overall project budget reasonably.
Green & Environmentally Friendly Material
All steel components are 100% recyclable after the end of building service life, producing less construction waste during installation. The production process strictly complies with international environmental standards, meeting the green building requirements of European, Australian, Southeast Asian and Central Asian markets.
Complete Technical & After-sales Support
We can provide complete material test certificates, fabrication inspection reports and construction installation manuals. Our technical team offers remote drawing review, structural scheme optimization and on-site installation guidance services. All specifications follow international building codes such as AS/NZS, Eurocode and GB standards.

Product Details

1. Product Overview

Prefabricated hot-dip galvanized steel structure building is a new type of modular building system, mainly composed of welded H-beam main frames, secondary beams, angle steel bracings, channel steel purlins, square & rectangular tube wall and roof supports, plus matched metal wall & roof panels. All steel parts are processed and galvanized in factory in advance, then transported to the construction site for fast bolt assembly without complex concrete pouring. This building type has become the mainstream choice for industrial, commercial and logistics construction projects all over the world.

2. Main Raw Material & Surface Treatment

Main Material Grade: Q355B / Q235B structural steel, stable mechanical property, high tensile strength
Surface Treatment: Full hot-dip galvanizing (HDG) for all load-bearing steel components. The zinc coating thickness meets international anti-corrosion standards, perfectly adapting to coastal high-salt, rainy, humid and industrial corrosive environments.
- Included Components: Welded H-beam structural members, standard H-beams, angle steel parts, channel steel parts, round pipe & square rectangular hollow section fittings, round bar connectors and all loose bolted accessories.

3. Core Production & Delivery Lead Time

The total production cycle ranges from 60 to 90 working days counted from the date we receive your advance payment and confirmed construction drawings. The first batch of fabricated steel components will be ready for shipment within 60–70 days. All goods are packed reasonably for sea transportation to avoid deformation and scratch during long-distance ocean and inland transit. We will lock logistics freight for you in advance to evade the risk of rising shipping costs.

4. Wide Application Range

Industrial fields: Manufacturing workshops, processing plants, heavy machinery factories, auto assembly plants

Logistics storage: Large-span warehouses, cold storage buildings, distribution centers, container yards

Commercial public buildings: Exhibition halls, stadiums, shopping malls, multi-story office buildings

Agricultural & auxiliary buildings: Livestock barns, greenhouses, grain storage warehouses, farm machinery garages

Special projects: Overpass corridors, mine support buildings, temporary construction camps

5. Design & Fabrication Standard

Our structural design complies with multiple international mainstream standards, including Chinese GB standard, Australian AS/NZS standard, European Eurocode and American AISC standard. We accept customers’ independent drawing standards for customized production. Every finished steel component will pass strict dimensional inspection, welding flaw detection and galvanizing thickness test before delivery, with complete inspection documents provided together with cargo.

6. Shipping & Document Rules

Bill of lading rule: If you do not specify to issue original bill of lading, we will arrange telex release by default. If the consignee marked on B/L contains "TO ORDER", only original paper bill of lading can be issued.
VGM regulation: All containers must submit VGM data before returning to the terminal yard; delayed VGM declaration will affect port stacking and loading schedule.
Order rule: No order cancellation is accepted once the production order is issued, as all steel materials will be cut and processed according to confirmed drawings immediately after order confirmation.

7. After-sales Service Commitment

Free drawing optimization and structural load calculation before order confirmation

Complete set of export documents: Commercial invoice, packing list, material MTR certificate, fabrication inspection report

Remote online installation technical guidance; support dispatching engineers to overseas construction sites for on-site instruction upon request

Long-term supply of spare steel accessories and replacement components for maintenance after project completion

Timely response to all technical and commercial inquiries within 24 working hours

8. Company Strength
