What is a steel structure workshop?

Steel structures are among the most cost-effective, durable, and widely used building materials today. Thanks to the superior properties of steel, a steel structure workshop offers significant advantages such as wide spans and lightweight construction.

In designing a steel structure plant, high-strength steel is typically used. This allows the building to resist harsh external weather conditions while ensuring the safety of both personnel and equipment inside.

Components of a Steel Structure Workshop

1. Embedded Components (Main Structure)
Embedded components are typically divided into two connection types: embedded bolt connection and insert-type cup mouth connection. In most standard steel structure workshops, the common method is the embedded bolt connection, which can be further classified into hinge connections and rigid connections.

Embedded bolts are generally L-shaped steel rods, with their diameter and length determined by specific design requirements. The typical diameter range is φ24–φ64 mm, and a single bolt can provide a tightening force of up to 300 kN, ensuring strong and reliable structural stability.

2. Steel Columns and Beams
The columns and roof beams of a steel structure workshop are usually fabricated from section steel or H-section steel made of steel plates. When posts and beams are welded from steel plates, they must be carefully corrected after assembly and welding to avoid deformation of the H-beams caused by welding stress.

As the primary load-bearing components of the workshop, steel columns and beams are typically connected by either welding or bolting, ensuring stability, strength, and long service life of the entire structure.

3. Substructure
The substructure of a steel structure workshop mainly includes purlins, wall beams, supports, and pull strips, which together enhance the overall stability of the building.

• Purlins and Wall Beams
  These are typically made of C-shaped or Z-shaped steel, with section sizes determined by load calculations. The spacing between purlins should not exceed 1.5 meters from the main beam, ensuring adequate support for the roof and walls.

  
  

• Supports
  The support system consists of roof supports and column cross supports, commonly fabricated from round steel, angle steel, or square pipes. These elements play a crucial role in stabilizing the steel frame and improving resistance to lateral forces.

  
  

• Pull Strips
  Pull strips are installed between purlins to regulate and control their relative stability. They are usually designed as sag rods made of round steel with a diameter of 12–14 mm, effectively preventing excessive displacement.

4. Roof and Wall Panels
The roof and wall panels of a steel structure workshop are generally classified into corrugated panels and sandwich panels, each serving different functional needs.

• Corrugated Panels
  Also known as monochrome panels, these are commonly used in buildings that do not require thermal insulation. They rely on purlins or wall beams to form the roof and wall enclosure, offering a cost-effective and lightweight solution.

  
  

• Sandwich Panels
  Sandwich panels are widely applied in buildings that demand thermal insulation and energy efficiency. Their core materials typically include polystyrene (EPS), polyurethane (PU) foam, rock wool, and glass wool, which provide excellent performance in heat preservation, sound insulation, and fire resistance.
