Short Description:

Steel structures utilize steel beams, columns, and trusses as their primary load-bearing framework. They are strong, lightweight, and durable, and modern steel treatments provide excellent corrosion resistance. They also offer superior seismic performance, making them suitable for earthquake-prone areas. They can also be prefabricated in modularized form, allowing for fast construction and flexible space. Steel is 100% recyclable, environmentally friendly, and in line with green building trends, making it widely used in various types of buildings.

    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.

     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.

    Application

    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. 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.

    Surface Treatment

    A wide variety of surface treatment processes are available for , 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.
