Description
A steel structure building factory designed for manufacturing production lines, with integrated overhead-crane runways, heavy-duty floor zones, process-heat ventilation, natural roof lighting and an office mezzanine. The frame is engineered around the buyer's equipment layout, crane duty and local climate.
Product Parameters
Features: Overhead crane runway 5–50 t integrated into the frame; production-line bay spacing; high eave for equipment; ridge skylight and ventilation for process heat; office mezzanine and truck docks
Application: Machining and assembly plants, light industrial factories, processing workshops, workshops with overhead cranes, and plant-and-equipment halls
Type: Portal frame or twin-bay steel structure with crane runway beams
Raw Steel Material: Q355B (S355JR / A572 Gr.50 equivalent); secondary members Q235B
Surface Treatment: Hot-dip galvanized 275 g/m² per ISO 1461, or painted per ISO 12944
Service Life: 50 years design service life
Wall And Roof: Sandwich panel (EPS / rock wool / PU) or single-skin corrugated steel sheet
Design Standard: GB 50017 / AISC 360 / EN 1993 (per project)
Span: 18–30 m single or twin-bay
Eave Height: 8–15 m to suit crane hook height
Project Description
This factory hall is framed with welded Q355B H-section portal frames in a single or twin-bay layout of 18–30 m span and 6–9 m bay spacing, with eave height set by the required crane hook and equipment height. Crane runway brackets are built into the columns so a 5–50 t overhead bridge crane can travel the full production length, and column sections are upsized for the lateral and longitudinal crane surcharge. The production floor zone is laid out around the buyer's line layout, with a separate office, canteen and toilet block on a steel mezzanine at one end. Continuous ridge skylight strips and exhaust fans or a roof monitor remove process heat and provide daytime natural light, while insulated wall and roof panels control heat loss. Loading docks and roller or sectional doors at the end bays let raw material and finished goods move through the building. Design follows GB 50017 with wind, snow, crane and seismic loads per the site code; steel consumption typically runs about 25–40 kg/m² for a crane-served factory, depending on lifting duty and span.
To receive free drawings & a quotation: please provide length × width × eave height plus local wind speed (m/s), snow load (kN/m²) and seismic zone; overhead crane tonnage and working duty, production line layout and floor loads, process heat load, and dock / door sizes. Our engineers will design the building to the wind / snow / seismic loads of your local code and return a detailed quotation within 48 hours.
Product Advantage
1. Crane runway integrated into the column design from the start, so the frame is sized for the lifting duty rather than retrofitted
2. Bay spacing and eave height arranged around the production line and equipment footprint
3. Ridge skylight and ventilation monitor sized to process heat for a workable interior
4. Office mezzanine and dock block bundled into one frame, avoiding a separate annex structure
5. Made-to-order Q355B frame designed to the local wind, snow and seismic code
6. Fabricated under ISO 9001 with weld and coating inspection records per EN 1090 / AWS D1.1
Factory Capability
Factory members are fabricated in our own H-beam and box-column workshop on automatic welding lines, with plasma cutting, C/Z purlin roll-forming and NDT inspection. Shop welding follows AWS D1.1 and GB 50205, dimensional tolerance is controlled to EN 1090 execution class, and material and weld records are kept under our ISO 9001 quality system.
Installation
Each order ships with erection drawings, bolt lists and part marks; our engineers provide online training and remote video guidance, and an on-site supervisor can be arranged. Anchor bolts are sent ahead so the heavier crane-column foundations can be poured and the frame raised in the agreed erection sequence.
Packing & Loading
Members are bundled in erection sequence and tagged by part mark, with crane runway beams and long members packed for break-bulk or container loading. All parts are packed to export seaworthy standard, loading photos are taken before shipment, and a packing list with shipping marks accompanies every delivery.
