ⅠWhat is a steel structure workshop?

Steel structure workshop is an industrial building that uses steel (such as H-shaped steel, C-shaped steel, steel plate, etc.) as the main load-bearing frame, which is connected by welding or bolts to form an overall frame, and is equipped with a protective system (such as color steel plate, sandwich panel).

ⅡComponents of Steel Structure Workshop

1. Main structural system

Main steel frame :
Steel column : A vertical load-bearing member, usually H-shaped steel or box-type column, supporting the roof and crane loads.
Steel beam : A transverse load-bearing member (such as an H-beam) that connects steel columns to form a frame and transfers loads.

Substructure :
Purlin : C/Z steel, supporting roof and wall panels, fixed to the main beam.
Support system : round steel or angle steel cross-bracing to enhance wind and earthquake resistance.

2. Enclosure system

Roofing system :
Roof panel : single-layer color steel plate or thermal insulation sandwich panel (rock wool/PU), waterproof and heat-insulating.
Skylight/ventilator : Improve lighting and ventilation in the factory.

Wall system :
Wall panels : Color steel plates, sandwich panels or metal carved panels, combining beauty and protection.
Doors and windows : Special doors and windows for steel structures(anti-deformation design).

3. Auxiliary facilities

Crane beam system : used to install overhead cranes (such as I-beam track beams).
Floor decking : corrugated steel plate + concrete composite floor, used for multi-storey factories.
Drainage system : gutters, downspouts (stainless steel or PVC).
Fireproof and anti-corrosion layer : fire-retardant paint, galvanized layer or weathering steel.

Ⅲ. Advantages of Steel Structure Workshop

High strength and lightweight
Steel is 3-5 times stronger than concrete and has a light weight (reducing foundation costs by approximately 30%).

Fast construction speed
Factory prefabricated components and on-site assembly construction shorten the construction period by more than 50% compared to concrete structures.

High space utilization
The span can reach 30-60 meters (without intermediate columns), which is suitable for the layout of large equipment.

Environmentally friendly and recyclable
The steel recycling rate exceeds 90%, reducing construction waste.

Flexible transformation
Easy to expand (such as adding floors, expanding), and convenient pipeline layout.

IV. Main Application

Industrial Manufacturing
Automobile factories, machining workshops (requires large space and high load capacity).

Warehousing and Logistics
E-commerce warehouses, cold chain logistics centers (quick construction, low cost).

Special Environment
Chemical plant (corrosion-resistant design), high-temperature workshop (fire-resistant steel + fire-retardant coating).

Agriculture and public facilities
Greenhouses, gymnasiums, hangars (large span requirements).

V. Comparison with other structures

Characteristic	Steel structure workshop	Concrete structure workshop
Construction period	3-6 months	8-12 months
Span Capability	Up to 60 meters	Generally ≤30 meters
Shock resistance	Excellent (good ductility)	Poor (brittle failure risk)
Maintenance costs	Regular anti-corrosion is required	Low
Environmental protection	High (recyclable)	Low (large amount of waste after demolition)

VI. Notes

Design stage : special conditions such as snow load, wind load (coastal areas), crane dynamic load, etc. need to be considered.
Anti-corrosion and fireproof : Aluminum-zinc plate or epoxy resin coating is required in humid or corrosive environments.
Thermal expansion and contraction : reserve expansion joints (one every 60 meters) to prevent temperature deformation.
Economic optimization : give priority to the use of standardized components (such as national standard H-shaped steel) to reduce processing costs.
