Description
Prefabricated Fabricated Steel Structure Workshop and Factory
Product Overview
Our prefabricated steel structure workshops and factories are engineered for industrial applications with superior durability and performance.
  • Primary Structural Framing: Built with high-strength H-Beam Q355B steel sections, coated with specialized industrial paint to establish a highly durable, rigid load-bearing frame.
  • Secondary Grid System: Roof and wall purlins utilize Q235B C-Section steel profiles, upgraded with a heavy-duty 275g galvanized layer to prevent atmospheric weathering.
  • Tension & Bracing Layout: Incorporates Φ20 steel cross bracings, L50*4 corner braces, Φ20 intercolumn bracing systems, Φ89*3 heavy tie rods, and Φ12 round steel stretchers.
  • High-Strength Fasteners: Pre-engineered components are secured on-site using Grade 10.9 high-strength intensive bolts, Grade 4.8 ordinary galvanized hardware, and heavy-duty Q235B foundation anchor bolts.
  • Industrial Weatherproofing: Features customizable Galvalume color plates or insulated sandwich panels for cladding, integrated with stainless steel drainage gutters, Φ110 PVC downpipes, and Φ600mm 304SS unpowered roof ventilators.
Product Advantages
  • Optimized for Factory Equipment: High-tensile Q355B H-beams deliver expansive clear spans, allowing seamless layouts for heavy machinery production lines, assembly bays, and overhead cranes.
  • Superior Anti-Corrosion Barrier: The 275g galvanized layer on the wall and roof purlins delivers long-lasting protection against industrial fumes, ambient moisture, and rust.
  • Engineered Stress Distribution: The comprehensive combination of tie rods, stretchers, and cross-bracings allows the pre-fabricated factory structure to withstand severe wind loads and seismic shifts.
  • Eco-Friendly Manufacturing Climate: Integrated Φ600mm stainless steel unpowered ventilators continuously exhaust smoke, heat, and pollutants from the factory floor without consuming electricity.
  • Rapid Turnkey Pre-Fabrication: Bolt-together connections using Grade 10.9 hardware eliminate extensive on-site cutting and welding, reducing workshop construction schedules and labor budgets.
Application Scenarios
  • Automotive Assembly Plants: Massive pre-fabricated industrial workshops featuring expansive floor layouts for multi-stage robotic vehicle assembly lines and parts stamping.
  • Heavy Machinery Workshops: Rigid factory buildings specifically engineered to house overhead bridge cranes, heavy CNC machining equipment, and industrial steel fabrication.
  • Electronic Manufacturing Facilities: Clean, climate-controlled prefabricated workshops built with high-insulation sandwich panels to safeguard precision microelectronics and cleanroom spaces.
  • Agricultural Processing Factories: Highly ventilated, pest-resistant steel structures designed for food milling, automated crop sorting, and large-scale bulk packaging operations.
  • Chemical Production Workshops: Corrosion-resistant industrial facilities utilizing 275g galvanized grids and stainless steel drainage systems to withstand chemical processing vapors.

Frequently Asked Questions
Q1: What structural elements make this steel building suitable for heavy factory machinery?
The main building skeleton utilizes heavy-duty Q355B H-beam steel profiles, which offer superior load-bearing capacity compared to standard steel. The framework is locked together with Grade 10.9 intensive bolts and anchored securely to the concrete base using Q235B anchor bolts to eliminate vibration and sway.
Q2: How does the factory roof manage ventilation and air quality during high-heat manufacturing?
The roofing architecture comes standard with Φ600mm 304 stainless steel unpowered ventilators. These units operate without electricity, using natural air currents and internal thermal pressure to pull hot air, smoke, and industrial exhaust out of the workshop automatically.
Q3: Can we choose high-performance insulation panels to maintain temperature control inside the workshop?
Yes. While the building envelope can be configured with standard Galvalume color steel sheets, you can upgrade both the roofing and exterior wall panels to high-insulation sandwich panels (such as Rockwool or Polyurethane) to enhance climate control and reduce factory HVAC operational costs.
Q4: How does this prefabricated steel framework resist rust in chemically active manufacturing environments?
All secondary structural components, including the roof and wall purlins, are crafted from Q235B C-Section steel featuring a thick 275g galvanized coating. The main H-beam frames are coated with specialized industrial paint, and the drainage system utilizes stainless steel gutters to completely prevent corrosion.
Q5: Are the components fully prefabricated before arriving at the industrial site?
Absolutely. All columns, rafters, purlins, and bracing networks are cut, drilled, and painted at the factory according to your engineering drawings. They arrive on-site ready for immediate assembly using the included Grade 10.9 high-strength bolts and Grade 4.8 ordinary bolts, minimizing welding.
