Product Description
What is a Pre-engineered Steel Building?
Pre-engineered steel buildings are structural systems built over a concept of primary members, secondary members, and roof/wall sheeting connected to each other. These buildings can include additions like skylights, turbo vents, mezzanine floors, and crane systems based on specific requirements.
Model of pre-engineered steel buildings
Applications & Scope

Pre-Engineered Buildings (PEBs) offer flexible solutions with low cost, high durability, and fast erection. Common applications include:

Industrial

Factories, Workshops, Warehouses, Cold Storages, Steel Mills, Assembly Plants.

Commercial

Showrooms, Supermarkets, Offices, Shopping Centers, Logistic Centers.

Public & Others

Schools, Hospitals, Stadiums, Aircraft Hangars, Farms, Pump Stations.

Industrial Application Commercial Application
Core Advantages

1. Cost Savings

Price per square meter can be 25%-30% lower than conventional steel buildings. Lower site erection costs due to faster processing.

2. Quick Erection

All components are factory-fabricated. Requires 60% less construction time compared to traditional reinforced concrete buildings.

3. Flexibility

Easy to expand in the future, low transportation costs, and versatile design options.

4. Energy Efficiency

A green solution with CO2 reduction, high recyclability, and excellent energy efficiency.

Structural Components
Primary Members / Main Frames:

Includes columns and rafters which are the main load-carrying supports. Shapes and sizes vary based on application.

Primary Structural Members
Secondary Members:

Purlins, girts, eave struts, and bracing made from cold-formed steel with high yield strength (345 MPa).

Roof & Wall Panels:

Standard thickness of 0.3mm to 0.6mm. Hot-dipped galvanized with zinc or zinc-aluminum coating for corrosion resistance.

Manufacturing & Quality Control
Material Receiving: Verification of MTC and dimensional inspection (length, width, thickness).
Preparation: CNC fire-cutting and automated drilling for high precision.
Welding: Utilizing Submerged Arc Welding (SAW) and MIG welding as per GB50661-2011 standards.
Shot Blasting: Cleaning to Grade SA 2.5 to ensure perfect paint adhesion.
Painting: Airless spray application with controlled WFT (Wet Film Thickness).
Fabrication Process Welding Process Blasting Process
Welding Standards:

Strict adherence to fillet weld size regulations (K size). Minimum fillet weld size K ≥ 1.5√t. Maximum size K ≤ 1.2t.

FAQ
What are the primary materials used in the steel frame?
The primary frame usually consists of H-section steel, while secondary members use C or Z-section purlins. All steel typically meets Q235 or higher grade standards.
How long is the warranty for these steel buildings?
These structures come with a 30-year limited warranty, ensuring long-term durability and structural integrity.
Can the design be customized for specific sizes?
Yes, all pre-engineered steel buildings are custom-designed according to the specific requirements of the customer and the site conditions.
What are the main benefits of PEB over concrete buildings?
PEBs offer approximately 60% faster erection time, 25-30% lower costs, and better flexibility for future expansions.
How is the steel protected against corrosion?
The steel undergoes shot blasting to Sa2.5 grade, followed by high-quality primer and finish paint coats, or hot-dipped galvanization.
What certifications do these buildings meet?
The manufacturing processes and products are certified by ISO9001, CE, SGS, and BV, following international quality standards.
