Pre-engineered Structural Steel Industrial Building Construction

What is Pre-engineered Steel Building?

Pre-engineered steel buildings are steel structures built over a structural concept of primary members, secondary members, roof and wall sheeting connected to each other and various other building components.

These buildings can be provided with different structural and non-structural additions such as skylights, wall lights, turbo vents, ridge ventilators, louvers, roof monitors, doors & windows, trusses, mezzanine floors, fascias, canopies, crane systems, insulation etc., based on customer requirements. All steel buildings are custom designed to be lighter in weight and high in strength.

Pre-engineered Steel Building Models

Applications of Pre-engineered Steel Buildings

Pre-Engineered Buildings are the most flexible solutions for contractors and owners. With advantages of low cost, high durability, perfect quality control and fast erection; PEBs are used for various applications.

Industrial: Factories, Workshop, Warehouses, Cold Storages, Steel Mills, Assembly Plant

Commercial: Showrooms, Supermarkets, Offices, Shopping Centers, Exhibition Halls, Restaurants, Logistic Centers, Multi-purpose Buildings

Public: Schools, Hospitals, Conference Halls, Laboratories, Museums, Stadiums

Others: Farms, Utility Shelters, Pump Stations, Aircraft Hangars, Airport Terminals

Why Choose Pre-engineered Steel Buildings?

1. Cost Savings
Price per square meter can be 25%-30% lower than conventional steel buildings. Site erection cost is low because of faster erection times and easier erection process.

2. Quick Erection
All steel components are fabricated at the factory and linked by bolts at the site. So the erection process is fast, step by step, easy to install and requires simple equipment. 60% less construction time required compared with traditional R.C.C (reinforced concrete) building.

3. Flexibility
Pre-engineered steel buildings are flexible in any requirement of design, easy to expand in the future and also economically with low transportation costs.

4. Energy Efficiency
Nowadays, pre-engineered buildings are the green solution for the environment with CO2 reduction, energy efficiency, and recyclability.

Components of Pre-engineered Steel Building

Primary Members / Main Frames
Secondary Members / Cold Formed Members
Roof & Wall Panels
Accessories, Buyouts, Crane System, Mezzanine System, Insulation, etc.
Sandwich Panels

Primary Members / Main Frames

Primary members are the main load carrying and support members of a pre-engineered building. The main frame members include columns, rafters and other supporting members. The shape and size of these members vary based on the application and requirements.

Secondary Members / Cold Formed Members

Secondary structural framing refers to purlins, girts, eave struts, wind bracing, flange bracing, base angles, clips and other miscellaneous structural parts. Purlins, girts and eave struts are cold formed steel members which have a minimum yield strength of 345 MPa (50,000 psi) and will conform to the physical specifications of GB/ISO/CE or equivalent.

Roof & Wall Sheets/Panels

Standard steel panels are 0.3, 0.4, 0.5 mm or 0.6 mm thick and have a minimum yield strength of 345 MPa. Steel panels are hot dipped and galvanized with zinc or zinc-aluminium coating. The base material is pretreated, before applying a corrosion resistant primer and top coat. The combined thickness of the painted film is 25 microns on the front side and 12 microns on the reverse side.

Other Building Accessories

Other building accessories include anchor bolts, fasteners (bolts, nuts, turnbuckle, expansion bolts), gutters, downspouts, doors, windows, ventilators, skylight panels, louvers and all other building-related materials.

Manufacturing Process and Quality Control

A: Material Receiving Procedure

Verify receiving documents and quantity of received material
Submit load for QC inspection
Visual inspection for surface condition and damages

Quality Standards & Control

With 20 year warranty in the steel building industry, our company maintains strict quality standards. We have acquired ISO9001 and CE certificates. Following are the related standards we strictly follow for design and fabrication:

GB/T1591-2008/2018
GB/T11263-2010
GB/T 2518-2008
GB/T12754-2006
GB/T 1228-2006

Fillet Weld Size Quality Control

Purpose: To ensure the quality of fillet weld, meeting technical requirements of welded members and improve standardization of fabrication.

Application Scope: Applying for design, fabrication and inspection of fillet weld size.

Fillet Weld Leg Size Requirements:

All fillet weld size should not be less than drawing and design values
Minimum fillet weld size K≥1.5×t (t = thickness of thicker welding member)
Maximum fillet weld size K≤1.2t (t = thickness of thinner welding members)
When t≤4mm, minimum fillet weld size same with member thickness
For fillet weld without groove, should not be more than 17mm
