How is the steel structure manufacturing process carried out? Steel structure is increasingly widely used thanks to its outstanding advantages in durability, flexibility and fast construction in civil and industrial works. Join Hai Long Steel Structure to explore in detail the 10 steps to produce standard steel structure right below.
1. Overview of Steel Structure
1.1 / What is steel structure?
Steel structure is the main load-bearing system of construction works, designed and constructed mainly from steel components such as columns, beams, trusses, braces and bolted or welded joints. This type of structure is increasingly widely used in industrial and civil construction thanks to its outstanding advantages of durability, high load-bearing capacity, light weight and quick construction.

1.2 / Popular types of steel structures
Frame Structures
- Description: The main load-bearing system is made up of steel columns and beams, linked together into a solid frame.
- Advantages: Good load-bearing capacity, large span, easy to expand the scale of the project.
- Applications: Factories, warehouses, plants, high-rise buildings, shopping centers.
Truss Structures
- Description: Constructed from steel bars connected in a triangular mesh pattern, helping to distribute the load evenly.
- Advantages: Light weight, good load bearing capacity, large span without needing many support columns.
- Applications: Gymnasiums, stadiums, canopies, theaters, airports.
Arch Structures
- Description: Using steel bars bent into arches, bearing mainly horizontal force.
- Advantages: Creates large space, high aesthetics, effective force distribution.
- Application: Warehouse, factory, gymnasium, exhibition hall.
Tube Structures
- Description: Using hollow steel pipes, with good anti-twist and load-bearing capacity.
- Advantages: Light weight, easy to construct, good corrosion resistance.
- Application: Steel frame, water supply system, oil and gas, civil engineering works.
Profile Steel Structures
Common types:
- H/I shaped steel: High load-bearing capacity, used for main beams and columns.
- U, C shaped steel: Making purlins, auxiliary bars.
- L-shaped angle steel: Corner reinforcement, secondary connection.
- Z-shaped steel: Making purlins for roofs and walls.
- Steel plate: For floors, roofs, walls, and connecting plates.
Composite Structures
- Description: Combination of steel and concrete, taking advantage of the advantages of both materials.
- Advantages: Good load bearing capacity, increased durability, reduced costs.
- Application: Composite floors, composite beams, bridges and roads.
1.3 / Advantages of steel structure
Steel structures are increasingly popular in industrial and civil construction thanks to their many outstanding advantages compared to traditional materials such as reinforced concrete or wood:
- High strength and durability
- Fast construction, saving time
- Cost-saving
- Light weight, easy to transport and install
- Flexibility, scalability and repairability
- Optimize space usage
- Highly industrialized
- Good airtightness, waterproof and rustproof
- Environmental friendliness
2. 10 Steps of Steel Structure Production
2.1 / Step 1: Prepare and gather materials
- Choose steel and auxiliary materials that meet standards, have clear origin, and full quality certificates.
- Check material quality before storing, remove substandard materials.
- Classify, collect and store materials in separate areas to avoid environmental impact.
- Check and arrange material gathering area for convenient transportation and production.
- Ensure equipment and machinery are ready for the next production steps.
2.2 / Step 2: Cut steel according to design
After completing the technical drawings, the steel plates or steel profiles will be cut to the correct size and shape specified in the design.
There are two types of steel commonly used:
- Profiled steel (precast steel): Already has standard shapes such as H, U, C, just need to cut off the excess to fit the design.
- Composite steel: Cut from steel plates or coils, then assembled into components according to project requirements.
The cutting process requires high precision to ensure that the assembled components fit together without errors in the following stages.
Modern cutting technologies commonly used include:
- Automatic cutting by laser machine
- Plasma, oxy-gas cutting
- Circular saw, band saw
- Automatic slitting and crimping machine
After cutting, the steel plates will be checked for size again, removing unqualified parts before moving on to the next processing step.
2.3 / Step 3: Press and shape the details
- Details such as metal panels and partitions are pressed to form the exact shape according to the design.
- The pressing process uses large compressive force on the steel billet to change its original shape.
- After pressing, carefully check the size and accuracy of the part compared to the drawing.
2.4 / Step 4: Weld the parts into components
- During the assembly of steel parts into complete structures, a dedicated automatic welding system is used to ensure optimum precision and quality.
- Automatic welding helps create even, beautiful, durable welds and strong connections between parts, while minimizing errors due to human factors.
- After the welding process is completed, the components are thoroughly inspected for weld quality, straightness and angles to ensure all technical standards are met before moving on to the next production steps.
2.5 / Step 5: Adjust the structure
- After welding, the components need to be straightened with a specialized straightening machine. Straightening will help eliminate warping and ensure flatness and standard angles of the components.
- Then, it is necessary to check the flatness and squareness of the structure with a specialized measuring ruler.
2.6 / Step 6: Install the connecting details
- Auxiliary details such as bolts, rivets, welds, etc. are used to assemble and connect structural components.
- Bolts must be tightened with the correct force using pliers and specialized screwdrivers.
- Finally, it is necessary to carefully check the position and size of the sub-components before welding.
2.7 / Step 7: Finishing welding
In this step, additional details such as brackets, reinforcing ribs, stiffeners, etc. will be welded onto the assembled steel structure to complete the product.
The finishing welding process uses specialized welding methods to ensure a strong, durable and technically correct weld; at the same time, it enhances the load-bearing capacity and stability of the steel structure.
After welding, all welds are carefully inspected for strength, shape, penetration and aesthetics. If errors are detected, they must be corrected immediately to ensure product quality before moving on to the next stages.
This stage requires meticulousness, precision and high skills, contributing to the safety and longevity of steel structures.
2.8 / Step 8: Clean the surface
- Use shot blasting system to clean entire surface of components.
- Completely remove dirt, rust, slag that affect weld quality and paint color.
- The surface after cleaning must be dry, clean, rough and even.
2.9 / Step 9: Protective paint
- Primer 1-2 coats of anti-rust primer as a base for the structure.
- Spray paint with specialized PU paint with standard thickness.
- Paint helps protect structures from environmental influences, prolonging their lifespan.
2.10 / Step 10: Inspection before packing and shipping
- Check all components before packing and storing.
- Steel structure is carefully preserved to avoid scratches and strong impacts.
- Transport to the installation site safely and properly.
