Fast Construction Structural Steel Building for Car Repair Workshop

Prefabricated steel structures are suitable for various scenarios such as industry (warehouses, workshops), commerce (exhibition halls, supermarkets), agriculture (agricultural machinery sheds), aviation (hangars), etc. The core consists of four major systems:

Ⅰ. System composition

Main framework system: carries the main load of the building, including steel columns, steel beams, and supporting components;
Sub frame system: auxiliary components such as purlins and perimeter beams to enhance structural stability;
Enclosure system: roof and wall cladding, with both waterproof and insulation functions;
Functional accessories: doors and windows, ventilators, drainage ditches, etc., to enhance the user experience.

Ⅱ. Technical parameters of core components

1. Main framework system
Column/beam specifications:
Steel beam: HN350 × 200 × 6 × 12 (height 350mm, flange width 200mm, web thickness 6mm, flange thickness 12mm), material Q345B, single span bearing capacity up to 20kN/m;
Steel column: optional H300 × 300 × 8 × 10 equal section, connected by end plate bolts (10.9 grade high-strength bolts), with installation accuracy error ≤ 2mm.
2. Sub framework system
Size of purlin:
C200 × 70 × 20 × 2.0 (height 200mm, rolled edge 70mm, return edge 20mm, thickness 2.0mm), material Q235B, spacing ≤ 1.5m, supporting roof and wall cladding;
Supporting components:
Wind resistant support: made of φ 20 round steel, forming a triangular stable system;
Wing edge support: ∠ 75 × 6 angle steel to enhance the torsional stiffness of the beam end.
3. Enclosure system
Coating material:
75mm EPS sandwich panel (bulk density 12kg/m ³), panel made of 0.5mm color steel plate (coating thickness ≥ 20 μ m), thermal conductivity ≤ 0.041W/(m · K), fire rating B2;
Waterproof design:
The roof slope is 5% -10%, equipped with color steel plate gutters (thickness ≥ 2mm) and PVC downspouts (diameter 110mm), with a drainage efficiency of 5L/s · m.

Ⅲ. Performance advantages and customization options

1.Core performance
Wind and earthquake resistance: Wind resistance level 10 (wind pressure ≥ 0.5kN/㎡), seismic fortification intensity 7 degrees, meeting the safety requirements of most regions;
Durability: The main structure is hot-dip galvanized for corrosion protection (zinc layer thickness ≥ 85 μ m), with a design life of 50 years, and EPS sandwich panels are maintenance free for 10 years.
2.Flexible customization
Material upgrade: Can be replaced with 100mm rock wool sandwich panel (fire-resistant grade A), or polyurethane sandwich panel (thermal conductivity ≤ 0.024W/(m · K));
Function extension:
Hangar scene: Install 5-30 ton crane tracks, and use electric sliding doors (width ≥ 12m) for the main entrance;
Warehouse scenario: Install ventilation ridges (with a ventilation rate of ≥ 12 times/hour), and install high-level lighting windows on the walls (with a light transmittance rate of ≥ 80%).

Ⅳ. Professional services 

In the pre-sales stage: our design team will deeply understand your project requirements, combine site conditions and functional positioning, and provide practical and economical design solutions. Whether it is spatial layout planning or structural form selection, we will carefully consider them from a professional perspective.

In the sales process:we strictly control production and logistics transportation. At the factory end, all components are processed and manufactured according to standardized procedures to ensure process accuracy and product quality; In terms of logistics and transportation, we will develop professional packaging plans based on the characteristics of the components, select suitable transportation methods, track logistics progress throughout the process, and keep you updated on the dynamics of project materials at any time.

In the after-sales stage: we provide professional installation and debugging services. The experienced installation team will carry out orderly construction according to the design drawings, and after completion, conduct comprehensive debugging of the overall system to ensure the normal operation of the building's functions. In addition, we will provide you with usage training and follow-up maintenance support, so that you have no worries.

From design concept to project completion, every step embodies our pursuit of quality, committed to creating a worry free and reassuring one-stop service experience for you.
