CE Certified Large Span Pre-engineered Steel Structure Multi-Storey Steel Storage Warehouse Building

Steel structures are fully fabricated as designed in accordance with the specifications of the customer, shipped to site in completely knocked down condition; and assembled and erected at site. These steel structures are pre-designed using computer aided design analysis into standard sizes, spans, bays and heights. And use standard details for fixing purlins, cladding, roofing gutters, flashing, windows, doors, etc. taking advantage of industrial practices of mass production of components economically.

The steel structure building includes following parts:

• Steel main frame
  If the building is hundreds of square, it will be according to the wind speed to calculate the main frame -- Square tube or H steel section.
• Secondary frame
  Steel structure building's secondary frame will be galvanized square tube or C purlin according to building’s size and wind load.
  Secondary supporting part mainly refer to C/Z section or square tube steel purlins and bracing system for prefabricated steel structure construction building.
• Roof and wall cladding system
  Usually, steel structure building's cladding will be corrugated steel sheet or sandwich panel, depending on customers' requirements.
• Doors & windows system
  It usually use rolling shutter door, sliding door and aluminium sliding window.

If you already have the architectural drawings, please send them to us and we will quote directly for you.

If you do not have drawings, only a plan or idea, please contact us, we have professional technicians according to your requirements and the conditions of your region to design, and offer quotations. Please kindly inform us of the following information, we will design for you as soon as possible:

• The local site Max. wind speed;
• Snow load if there is snow in local;
• Size of the building (length*width*eave height);
• Roof and wall material;
• There is crane inside the building or not; If have, pls confirm the lift tons;
• Drawing or more specification if have.

Why choose steel structure building?

• Widely used
  Steel structure building can be used in factory, warehouse, workshop, office building, gymnasium, aircraft hangar and so on. It is suitable for single-storey long-span buildings as well as multi-storey or high-rise buildings.
• Short construction time
  Large span steel structure building construction is simple and its period is short. All the components are manufactured in the factory and only need to be assembled on the site, which greatly reduces the construction time.
• Durable and easy to maintain
  Large span steel structure building can withstand harsh weather and require only simple maintenance.
• Beautiful and practical
  Steel structure building lines simple and smooth, with a modern feeling. Chromatic wall body board has a variety of color to offer a choice, wall body also can use other material, have flexibility more consequently.
• The cost is reasonable
  Large span steel structure building is light in weight, which can reduce the cost of foundation.

The processing of a steel structure structure involves a series of essential steps, including cutting, assembly, welding, rust removal, and surface treatment.

• Material Preparation
  Steel materials, such as beams, columns, and plates, are received and inspected for quality. They are organized and prepared for further processing.
• Cutting and Shaping
  The steel components are cut to the required sizes using cutting techniques like sawing, shearing, or plasma cutting. They are then shaped using processes such as bending, rolling, or pressing to achieve the desired form.
• Welding and Joining
  The individual steel components are joined together using welding techniques, such as arc welding or gas welding. This creates strong and secure connections between the different parts of the structure.
• Surface Treatment
  The steel components may undergo surface treatments like shot blasting or painting. These treatments help to remove impurities, improve the surface finish, and provide corrosion resistance.
• Quality Control and Inspection
  Throughout the processing stages, quality control measures are implemented to ensure that the components meet the required standards and specifications. Inspections are conducted to identify any defects or inconsistencies that need to be addressed.
• Packaging and Storage
  The finished steel components are carefully packaged and stored in the factory to protect them from damage and ensure their readiness for transportation.

Packaging Detail:
The packing method for main steel frame will use steel pallet, which can be better to protect steel frame and make the loading and unloading faster and more convenient since it could be taken as a whole. It could also save the quantity of shipping containers and cost of ocean freight.
Other parts packed in parcels such as steel purlin and steel sheet, all loaded into 40ft HQ. Safe and easy handle.

Anchor bolt installation:

• Anchor bolt site inspection; Bolts, nuts and washers should be oiled to protect and avoid to be rusted.
• Install the positioning plate; Recheck the plate holes position before installation;
• Install bolt group;
• Anchor bolt fixation;
• Bolt sets reinspection;
• Thread protection;
• Concrete pouring.

Anchor bolt will be pre-embedded according to final Anchor Bolt Drawing. It should use template install, positional deviation is ±5mm.
