Product Description

 

A prefabricated 2-storey steel structure building is an ideal choice for an industrial workshop or warehouse. This kind of design maximizes space utilization, allowing for separate areas on each floor to accommodate different workshop functions. 

 

It's an integrated ventilation system, which promotes optimal air circulation, regulates temperature, and removes fumes and moisture—creating a safer and more productive environment for any application.

This 2-story prefabricated steel structure building features an exceptional 9-meter height per floor, reaching a total height of 18 meters. The design element includes a three-story office space constructed at the corner of the steel building.

 

The main workshop area is covered by single steel sheets for walls and roofing, providing a durable and cost-effective enclosure. While the office section utilizes traditional brick walls. This material choice significantly enhances thermal insulation and soundproofing, creating a quiet and comfortable working environment for office personnel.

 

The large span, open-plan workshop is flooded with natural light, fostering a bright and productive atmosphere. This optimal layout ensures orderly, efficient, and high-speed production operations.

Our experienced design department has extensive practical expertise in completing the structural design of steel buildings in compliance with Chinese design codes and local regulations. Every design is optimized to ensure structural safety, reasonable layout, and cost-effective steel consumption.

 

For overseas projects, structural design must follow the local building codes and standards (such as Euro standards or US standards). We will provide the necessary drawings and detailing to support the local registered engineers in completing the design.

 

We also provide structural detailing, 3D modeling, fabrication drawings, and installation shop drawings, ensuring accurate and efficient construction.

 

Whether you need a warehouse, workshop, office building, or industrial facility, our steel structural design solutions provide strength, durability, and efficiency from concept to construction.

 

Step-by-Step Steel Building Construction Process

Construction Step

Description

1. Structural Design

Engineering analysis to determine load capacity, span, wind/snow resistance, and layout configuration.

2. Steel Fabrication

Prefabrication of columns, beams, purlins, and bracings based on custom design and material specs.

3. Welding & Processing

Welding and cutting components in the factory to ensure accuracy and efficiency.

4. On-Site Assembly

Bolting or welding frames, purlins, and cladding together according to construction drawings.

5. Roofing & Cladding

Installation of roof panels, wall panels, insulation, and waterproofing layers.

6. Final Finishing

Installation of doors, windows, gutters, ridge caps, and trim.
