China CT Steelstructure Co.,Ltd company profile

1.Raw material inspection and pretreatment:Professional quality inspection personnel will strictly inspect the steel and pre-treat the qualified steel, such as shot blasting and sand blasting, to remove impurities such as rust, oxide scale, and oil stain. In addition, professional leveling equipment is needed to ensure the flatness of the steel.

2.Cutting and blanking:Accurately cut according to the size and shape of the design drawings. We use CNC cutting equipment controlled by computer programs, such as CNC flame cutting machines, plasma cutting, laser cutting and other professional equipment to achieve automated cutting, which can meet the cutting requirements of complex shapes, and the error can be controlled within 0.1 mm.

3.molding processing:For some steel structural members with complex shapes such as bending and folding, forming processing is needed. Equipment includes plate bending machines, bending machines, etc. During this process, technicians will adjust the pressure, speed and other parameters of the equipment at any time to ensure the accuracy of forming.

4.welding assembly:Welding is to connect the cut and formed steel members into a whole. Before welding, the interface needs to be treated to ensure the penetration and strength of the weld. Select the appropriate welding method during the welding process. After the welding is completed, the weld seam is visually inspected and non-destructive tested.

5.coating protection:Before painting, the surface of the component needs to be cleaned again. The coating process includes three processes: primer, intermediate paint and top paint. Painting can be done by brushing, rolling, spraying and other methods. After the coating is completed, the thickness and adhesion of the coating need to be checked to ensure compliance with the design and specification requirements.

6.Finished product inspection and delivery:Conduct a comprehensive inspection of steel members in accordance with design drawings and relevant standards. For large or key components, load tests, deformation tests, etc. will also be carried out. All qualified components will be numbered, identified, packaged according to requirements, and finally attached with product quality certification documents.

In the development wave of the steel structure industry, we have the honor to reach in-depth cooperation with many companies and jointly launched a journey of mutually beneficial and win-win cooperation. This cooperation is not a simple business transaction, but is based on the high degree of compatibility between the two parties in terms of industry concepts and development visions. It builds an all-round and multi-level cooperation model from the collision of needs in the early stage of the project to the continuous collaboration in the later stage.
1.In the demand communication stage in the early stage of cooperation, we felt the company's rigorous attitude and high standard requirements for the project. In order to accurately grasp its core needs, we have formed a special docking team composed of senior sales, experienced designers and technical experts, and conducted multiple rounds of face-to-face communication with the company's project leaders.
2.Entering the plan design process, the in-depth collaboration between the two parties is particularly evident. Our design team fully absorbs the company's professional advice on production processes, R & D layout, etc., and integrates it into the design of steel structure plans. For example, according to the load-bearing requirements of its large-scale production equipment, the beam-column joint design of steel structures has been optimized; combined with the need for spatial flexibility in the research and development area, a detachable steel structure connection method has been adopted. During the design process, we established a real-time communication mechanism and held online meetings every week to provide timely feedback on the design progress and answer each other's questions. The final plan not only met various technical indicators, but also achieved breakthroughs in cost control and construction efficiency, and was highly recognized by many companies.
3.After the contract was signed, the project entered the implementation stage and the cooperation between the two parties was further deepened. During the production and processing process, we open the production workshop to allow the company's technicians to conduct on-site supervision and understand the production progress and quality status of steel structural members in real time.
4.During the on-site installation phase, we worked closely with the company's construction management team to establish a joint scheduling mechanism. A meeting was held in the morning to clarify the construction tasks and safety precautions for that day; a work summary was held in the evening to coordinate and solve problems that occurred that day.
5.When the project was completed and accepted, the company spoke highly of the quality, accuracy and overall effect of the steel structure project. After the industrial park was put into use, its solid structure and efficient spatial layout provided a strong guarantee for the company's production and research and development and greatly improved its operational efficiency.
These in-depth cooperation not only brought practical economic benefits to both parties, but also accumulated valuable cooperation experience. In the future, we will carry out more extensive cooperation with more customers in the fields of technology research and development, market expansion, etc., and work together to create a better future for the steel structure industry.

A.Materials technology research and development: breaking through the performance boundaries of steel

     • Research and development of high-performance structural steel:

According to the needs of different scenarios (such as long-span bridges, super high-rise buildings, and low-temperature environmental engineering), we develop high-strength low-alloy steel (HSLA steel, yield strength ≥460MPa) and ultra-high-strength steel (yield strength ≥690MPa), and adjust the alloy composition (such as adding vanadium, niobium, titanium) and rolling process (controlled rolling and cooling) to ensure strength while improving toughness (avoiding low-temperature brittle fracture) and reduce the amount of steel (reducing structural weight).

     • Functional steel innovation: Weather-resistant steel
     • By adding alloy elements such as chromium, nickel, and copper to form a dense oxide layer ("patina") to improve    atmospheric corrosion resistance. It is suitable for paint-free or low-maintenance scenarios such as bridges and outdoor factories to reduce corrosion prevention costs in the later period. Fire-resistant steel: It can still maintain a certain strength (such as yield strength ≥2/3 of the normal temperature value) at high temperatures (above 600℃). Grain growth is suppressed by adding molybdenum, niobium and other elements, and there is no need to spray additional fire-retardant coatings, simplifying the construction process. Green low-carbon steel: Develop low-energy smelting technologies (such as steel scrap for electric arc furnaces + hydrogen energy steelmaking) to reduce carbon emissions from steel production; explore performance stabilization processes for recycled steel to realize "scrap and new steel" recycling.

B.Research and development of production process and equipment: improving processing accuracy and efficiency

• Welding technology upgrade:

Welding is a key process for connecting steel structures. The research and development directions include: Efficient welding processes: such as narrow gap submerged arc welding (suitable for thick plate welding, groove width ≤20mm, reduce the amount of filler material, and increase welding efficiency by more than 30%), laser-arc hybrid welding (laser preheating + arc cladding, achieve High-speed welding, weld strength is increased by 10%-15%).

• Automated welding equipment:

Develop multi-axis robot welding workstations to adapt to batch welding of complex components and reduce quality fluctuations caused by manual intervention; develop continuous welding production lines for long and straight components (welding speeds up to 1.5-2m/min).

The R&D department leverages the expertise and resources from these support teams to ensure seamless integration of new technologies and processes into our product lines.

• Optimization of cold bending forming and cutting technology
• Component assembly and correction technology

Green manufacturing technology research and development: responding to low-carbon environmental protection requirements

• Energy efficient use technologies: Promote short-process steelmaking in electric arc furnaces, develop a frequency conversion speed control system for welding equipment (reducing no-load energy consumption by 30%) and a heating furnace waste heat recovery device (increasing thermal efficiency to more than 85%) to reduce energy waste in the production process.
• Waste recycling and treatment: Develop a welding smoke purification system to avoid dust pollution; classify and recycle cutting scraps and waste welding slag to achieve "zero waste" production; develop water-based anticorrosive coatings (VOC emissions ≤50g/L) to replace traditional solvent-based coatings to reduce Air pollution.
• Low-carbon production management: Establish a carbon emission monitoring system (real-time recording of energy consumption and emission data in steel procurement, welding, coating and other aspects), and combine blockchain technology to achieve carbon emission traceability; develop a "low-carbon component" certification system to meet downstream customers (such as green). The low-carbon needs of building projects).

​The technical research and development of steel structure production plants is a full-chain innovation of "material-process-design-manufacturing-management". Its core goals are: to adapt to the needs of scenarios with better material properties, reduce costs with higher production efficiency, and respond to environmental requirements in a greener way and improve market response speed with a smarter model. These R & D not only promotes the competitiveness of individual factories, but also drives the transformation of the entire steel structure industry from "traditional manufacturing" to "high-end intelligent manufacturing", providing more reliable and more for large-scale projects (such as super high-rise buildings, long-span bridges, and green buildings). Economic and lower-carbon solutions.
