Prefabricated Industrial Design Portal Frame One-Stop Solution Steel Structure Factory Building
The steel building is made of steel structures, including internal support and external enclosure structure. The steel frame is made of a portal steel frame, including steel columns, steel beams, and bracing. The portal steel frame and the external enclosure structure constitute an enclosed building structure with sufficient strength to withstand severe weather such as strong wind, rain, and snow.
Metal structures processed the cut, welded, drilled, and painted in the workshop, and then transported to the construction site, often referred to as prefabricated structures. The prefabricated steel structure does not need to be welded on-site, and each component only need to be fixed with bolts, which is convenient and quick to install and save labor. Five main types of structural components make up the steel frame-tension members, compression members, bending members, combined stress members, and their connections.
1) Column and Roof Beam: Q355B welded H section Beam
2) Crane Beam: Q355B welded H section Beam with a vertical
stiffening rib
3) Roof Horizontal Bracing: Q235B Steel Rod
4) Column X Cross Bracing: Q235B angle steel or steel rod
5) Roof Purlin: Q235B Galvanized Z section steel
6) Wall Girt: Q235B Galvanized C section steel
7) Sag rod: Q235B Galvanized steel rod
8) Roof Cladding: 0.5mm corrugated single color sheet with glass
wool insulation
9) Wall Cladding: 0.5mm horizontal corrugated single color steel
sheet
Wall and roof panel:
The roof panel is usually a single continuous length from the eaves
to the ridge line for portal frame buildings.
Wall panels are usually the continuous length from the bottom wall
to the eaves of the building.
It is usually a corrugated single-color metal sheet with a
thickness of 0.5mm-0.8mm. For a factory building that requires
thermal insulation, you can choose to use a sandwich panel.
Steel materials have many advantages over other building materials (such as wood)
The prefabricated steel structure is manufactured according to strict specifications and tolerances.
All materials are 100% recyclable.
The steel structure is not easy to warp, bend, twist, or bend, and is easy to modify and flexible in design.
Steel structure can improve building quality and reduce maintenance while providing higher safety and resistance.
Construction period
In terms of the construction period, the steel structure has
obvious advantages. The prefabricated steel structure building
construction is speedy because its construction is produced in the
factory on the construction site. Only hoisting and splicing can
meet some manufacturers’ needs for emergency construction and
warehouse construction.
Environmental protection
After the steel components are processed and transported to the
construction site, the components only need to be hoisted and
welded. There is no water operation, no sand, and a large amount of
dust generated during the whole process, which can reduce
environmental pollution and impact nearby residents. However, the
traditional concrete Buildings can’t do this, which means that
steel structures have done a good job in environmental protection,
the most important aspect of humanity. Besides, the recyclability
of steel also conforms to the concept of sustainable development.
In contrast to concrete buildings, after demolishing, there is a
pile of construction waste.
Price
Steel structure saves construction costs and labor costs more than
concrete. The cost of building made of steel structure is
20% to 30% lower than that of traditional concrete buildings, and
steel structure is stronger and more durable than concrete and has
the superior seismic performance.
Structural weight
The steel structure building itself has the characteristics of
lightweight. The prefabricated steel structure warehouse walls and
roof are made of light metal building materials, which are much
lighter than the brick and concrete wall ceramic tile roof, which
can reduce the warehouse’s overall weight and does not damage the
stability of the structure.

The fabrication procedure typically follows the below steps:
Measuring, cutting and welding the steel
Placing the holes and cleats in the correct position
Packaging and carefully loading in the right sequence
Dispatching to site and erecting if required.
Technical team:
Through years of accumulation and deploitation, we have formed a complete set of building system solution. KAFA's exceptionally talented engineering staff have earned a solid reputation. They are all qualified engineers, with structural expertise and extensive design experience. Our design engineers, skilled with advanced CAD and TEKLA software, will provide you with most dependable and economical building structure. Design considerations may include such factors as seismic, wind and soil bearing loads in relation to supporting structures and foundations. In other applications: corrosion allowances, specific gravity, slosh effect and equipment loads may need to be addressed. Whatever your concerns, we will analyze and design to your specific requirements and environments.
We believe technology makes a difference. By utilizing 3D detailing, Material Requirement Planning Software and CNC processing equipment, we are able to produce accurate drawings quickly, purchase material efficiently and process your job precisely.
A combination of in-house, domestic and foreign resources, techniques and technologies are utilised to meet our clients’ design requirements. With our experienced and well equipped estimating and project design team we ensure that anything is possible.
