Structural Steel Prefab Industrial House Construction Building Workshop Warehouse Prefabricated Steel Structure
Structural steel is a category of steel processed in a specific way to be used in the construction of buildings and bridges. It has a balanced chemical composition and high mechanical strength, and the mechanical properties are predictable, and because of its predictability for heavy load-bearing and stabilization in construction, it is broadly utilized.
Based on project specifications and standards, there are different dimensions and grades of structural steel available. It can be made by hot rolling or cold rolling or welding to fulfill the different requirements for structure. Typical structural steel products are I-beams, H-beams, wide flange beams, channels, angles, steel plates, etc., and they are used extensively in buildings, bridges, warehouses, factories, and utility projects.

Steel Structure Sections
Available sections are described in published standards worldwide, and specialized, proprietary sections are also available.
I-Beams / H-Beams:
I and H sections are compressed elements, and the two are commonly used for the construction of frames, bridges, industrial and heavy-load equipment. Typical standards would be universal beam (UB), universal column (UC), European IPE/HE sections and US wide flange (W-shape) beams.
Z-Beams:
Z sections have flanges that are offset and are popular for use in roofin systems, external wall framing, and other applications subject to light loads.
Hollow Structural Sections (HSS):
With a range including square, rectangular, circles and oval hollow sections HSS, its excellent strength to weight performance makes it the perfect solution for architectural structures, columns and steel frames.
Angles (L Sections):
Steel angles (L shaped) are established components within engineering projects such as E-15000 work, supports, bracing systems, towers, frames and even general works.
Structural Channels (C Sections):
C-channel also serve as joists spanning under floors and roof decking, beams of medium strength for purlins, and carrier beams for heavy duty automotive and industrial applications.
T-Beams:
Beam strengthened T steel profile is the most widely used in industrial, civil construction that require beams and floor systems in Columns.
Bars:
Steel bars are smaller and thinner strips of material compared to steel plates with rectangular cross-section and finds its application in Engineering, fabrication, and construction.
Rods:
Steel rods are round or square shaped products that find their application in construction reinforcement, mechanical components and fabrication works.
Steel Plates:
Plates are generally considered to be flat structural steel products thicker than 6 mm (1/4 inch), and are used widely in bridges, ships, heavy machinery, and large-scale steel construction.
Steel structures have steel as the main load bearing element. They have been applied as engineering materials in more and more fields for their high strength, light weight, rapid construction and good seismic performance. Its main application scenarios include:
Construction Engineering
1. Industrial Buildings - Factories: such as machining, metallurgy, chemicals, etc.
2. Warehouses: Large-scale logistics and storage facilities (such as high rack warehousing and cold chain warehousing);
3. Civil Buildings - High-rise Buildings: Steel structures of superhigh-rise buildings (such as skyscrapers);
4. Public Buildings: Stadiums, exhibition halls, theaters, airport terminals and the like.
5. Housing: A privative residential steel frame dwelling which is low-energy
Transportation Infrastructure
1. Bridge Engineering - Long-span bridges - Railway/highway bridges
2. Rail Transit and Stations - High-speed rail stations, subway station concourses - Rail transit vehicles
Unique Engineering and Equipment
1. Marine Engineering - Offshore Platforms: General configurations of oil drilling platforms (such as jackets and platform decks); Shipbuilding
2. Hoisting and Construction Machinery - Cranes - Special vehicles
3. Large Equipment and Containers - Industrial storage tanks - Mechanical equipment frames
Others Special Situations
1. Temporary buildings: prefabricated buildings.
2. The glass domes can be supported by the bought glass units for big shopping malls
3. Energy engineering:wind turbine towers (fabricated from hot rolled high strength steel plates) and solar panels.
Cutting Process
1. Preliminary Preparation
Material Inspection
Drawing Interpretation
2. Choosing the Appropriate Cutting Method
Flame Cutting: Suitable for thicker mild steel and low-alloy steel, ideal for rough machining.
Water Jet Cutting: Suitable for a variety of materials, especially heat-sensitive steel or high-precision, special-shaped parts.
Welding Processing
Welded steel framing is an important manufacturing and construction process, which enables the joining of separate steel members to form a solid unified framework._atomic bonds between steel surfaces at joints by the application of heat, pressure or the combination of these two, resulting in a solid and reliable joint.
Filler materials may be added during the welding process to increase strength and the quality of the joint. This technique finds very extensive application in the manufacture of steel buildings, bridges, industrial equipments, ships and heavy engineering structures, and has a direct effect on the overall rigidity, stability and safety of the steel structure. Good welding and quality control are necessary in order that the structural performance can be relied upon and that the structure can be expected to have a long service life.
Based on the construction drawings or welding procedure qualification report (PQR), clearly define the weld joint type, groove dimensions, weld dimensions, welding position, and quality grade.
Punching Processing
This process involves mechanically or physically creating holes in steel structural components that meet design requirements. These holes are primarily used for connecting components, routing pipelines, and installing accessories. It is a crucial process in steel structure manufacturing to ensure component assembly accuracy and joint strength.
Based on the design drawings, determine the hole position (coordinate dimensions), quantity, diameter, level of precision (e.g. ±1mm tolerance for normal bolt holes,±0.5mm tolerance for high-strength bolt holes) and hole type (round, oblong, etc.). With the help of a marking instrument (steel tape measure, stylus, square, or sample punch) mark the hole on the surface of the part. Use a sample punch critical holes to establish locating points/Dots must have accurate drill locations.
A wide variety of surface treatment processes are available for steel structure building, effectively enhancing their corrosion and rust resistance, as well as their aesthetic appeal.
Galvanizing is a classic selection due to the very good rust resistance.
With powder coating, rich colors and good weather fastness can be achieved.
Epoxy coatings have good corrosion resistance and can be used in aggressive environments.
A high zinc content makes the epoxy zinc-rich coating vulnerable to mechanical damage but it also provides good electrochemical protection.
Painting is flexible and economical, which can satisfy different decorative requirements.
Black oiling is a cheap solution for mild corrosion protection needs.
