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).
Common standard sizes：
1.Span
Standard span |
18m, 24m, 30m, 36m (larger spans require special design) |
Use impact |
24-36m is commonly used in machinery manufacturing plants, and 18-30m may be used in storage plants |
2.Column spacing
Conventional column spacing |
6m, 7.5m, 9m, 12m |
Enlarged column spacing |
18m (need to combine trusses or hollow beams to reduce steel consumption) |
3.Height
Eaves height |
8-15m for single-story plants, and the height of the top of the track with a crane must be ≥9m (such as 10t cranes require 10-12m, and 50t cranes require 15-18m) |
Clearance requirements |
Consider equipment height, ventilation ducts and lighting |
4.Roof slope
Common slope: 5%-10% (the slope in rainy areas should be ≥8%).

Ⅲ. Advantages of Steel Structure Workshop
Welding robot
Box-type intelligent manufacturing
Automatic profile processing
CNC cutting
CNC 3D drilling machine
Laser cutting
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
Power plant
Chemical plant
Hotel
Bridge
Commercial center
Cultural center
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.
