Our primary steel frames are manufactured for projects that require reliable load-bearing performance, large usable space, fast erection, and flexible customization.

They are suitable for a wide range of industrial and commercial construction projects, including warehouses, production plants, processing facilities, workshops, logistics buildings, storage centers, and prefabricated steel buildings.

Each steel frame can be produced according to customer drawings, project dimensions, design loads, structural specifications, and installation requirements.

Primary Steel Frame Configuration

Depending on the building design, the main frame may include:

• Welded H-section steel columns

• Tapered steel columns

• Steel roof rafters

• Heavy-duty steel beams

• Rigid frame joints

• Column base plates

• Flange connection plates

• Reinforcement stiffeners

• Anchor connection components

• High-strength bolted joints

Key Features

Strong Load-Bearing Performance

The primary frame is engineered as the principal load-carrying structure of the building and provides reliable resistance against vertical and lateral loads.

Flexible Structural Design

Frame dimensions, beam sizes, column sections, roof slopes, and connection details can be adjusted according to different building requirements.

Suitable for Large Buildings

Primary steel frames can be designed for wide-span buildings, helping reduce the need for excessive internal columns and improving space utilization.

Factory Prefabrication

Main structural components are cut, welded, drilled, inspected, and surface-treated before shipment, allowing faster and more organized installation at the project site.

High Dimensional Accuracy

Modern fabrication equipment helps maintain accurate hole positions, component dimensions, joint alignment, and structural consistency.

Easy Transportation and Assembly

Steel components can be divided into transportable sections and connected through designed bolted joints for efficient overseas shipping and on-site erection.

Available Customization

We can customize the primary steel frame according to:

• Building width and length

• Eave height

• Clear span

• Column spacing

• Roof slope

• Design load

• Steel section size

• Connection method

• Surface coating

FAQ

What is the difference between a primary frame and a secondary steel structure?

The primary steel frame carries the main structural loads and normally consists of columns and rafters. Secondary members, such as purlins, girts, and bracing, support the roof and wall systems and help stabilize the building.

Can you produce tapered steel columns and beams?

Yes. Built-up tapered steel members can be fabricated according to project drawings and structural requirements.

Can you manufacture only the main steel frame?

Yes. We can supply only primary steel frame components or provide a more complete steel building package depending on project needs.

What information is needed for a quotation?

For an accurate quotation, please provide structural drawings, building dimensions, steel specifications, required surface treatment, project location, and estimated quantity.

Can components be marked for installation?

Yes. Individual steel members can be marked according to erection drawings to help simplify identification and installation on site.
