Product Description

 Qingdao Chengchuan Construction Engineering Co., Ltd.

As a senior enterprise focusing on the prefabricated steel structure field, we are deeply engaged in the R&D, design, manufacturing, prefabrication and full-process delivery of Prefab Workshop, Industrial Shed, Metal Frame Warehouse and various Prefabricated Steel Structure products. With strong technical accumulation, standardized production strength and full-chain service capabilities, we provide safe, efficient, durable and environmentally friendly customized steel structure solutions for global customers in industries such as industry, logistics and manufacturing, interpreting the industrial value and application advantages of prefabricated steel structures with professional strength, and becoming a highly influential prefabricated steel structure solution provider in the industry.

We have established a professional team composed of senior steel structure engineers, prefabricated building designers and material R&D experts, focusing on the research and development of core technologies for prefabricated steel structures. Strictly following GB/T 51232-2016 "Technical Standard for Prefabricated Steel Structure Buildings", ISO international standards and international norms such as ASTM and BS, combined with the different application scenario needs of Prefab Workshop, Industrial Shed and Metal Frame Warehouse, we have realized in-depth integration and innovative upgrading of technology and products. Relying on professional design software such as SAP 2000, AutoCAD and Tekla, the R&D team carries out 3D modeling and finite element analysis, optimizes the design of structural nodes, overcomes core technical difficulties such as large span, lightweight, wind resistance and earthquake resistance, and can realize column-free clear span design from 15m to 150m, with eave height up to 6m to 40m, adapting to multi-level operation needs. At the same time, according to different scenarios such as industrial production and goods storage, we optimize the load design, which can meet the installation needs of 5-50 ton crane systems, with the maximum roof live load up to 250kg/ m², wind load can resist 200km/h strong wind, and the maximum seismic grade can reach 8, ensuring the structural stability and safety of products in various complex environments. In addition, we have established industry-university-research bases and R&D centers with universities, accumulated more than 100 utility model patents, and many core technologies have reached the leading level in the industry, continuously promoting the upgrading of prefabricated steel structure products to intelligence, efficiency and greenization.

Comprehensive service: design, manufacture, delivery, installation, and after-service.

Product Description

The company has a standardized intelligent production base, equipped with a full set of advanced production equipment such as laser cutting, precision welding, shot blasting derusting, automatic painting and prefabricated component production lines, realizing large-scale and refined prefabricated production of Prefab Workshop, Industrial Shed, Metal Frame Warehouse and various prefabricated steel structure components. The factory prefabrication rate is over 90%, which effectively avoids on-site construction errors and greatly improves delivery efficiency. We strictly follow the ISO9001:2015 quality management system, ISO14001:2015 environmental management system and ISO45001:2018 occupational health and safety management system, obtained international product certifications such as SGS and CE, and established a full-process testing mechanism from raw material procurement to product delivery.

The raw materials are all high-strength steel such as Q235B, Q355B and ASTM A36, with a yield strength of 345MPa to 460MPa, which have passed strict quality inspection; during the production process, advanced processes such as automatic submerged arc welding are adopted, the precision error of steel structure components is controlled at the millimeter level, and the surface treatment adopts multiple anti-corrosion processes such as shot blasting derusting (meeting SA 2.5 standard), hot-dip galvanizing (zinc layer thickness not less than 85μm) and advanced polymer coatings (PVDF/HDP finishes), which greatly improves the corrosion resistance of products and ensures the service life can reach more than 50 years. The company's annual production of various prefabricated steel structure components is 100,000 tons, the annual prefabricated building area can reach 2 million square meters, and the monthly production capacity can reach more than 2,000 square meters. It can not only efficiently meet the delivery needs of bulk orders, but also provide personalized customization services according to the customer's site conditions and usage needs, balancing mass production efficiency and customization flexibility.

Certifications

We have complete industry qualifications, including steel structure engineering professional contracting qualification, EPC general contracting qualification and relevant supporting qualifications. We have an experienced construction and installation team, proficient in the on-site installation process of Prefab Workshop, Industrial Shed and Metal Frame Warehouse. We adopt modular installation, no on-site welding is required, only bolt fixing is needed, and the installation is convenient and efficient. Compared with traditional concrete buildings, the construction period can be shortened by 40%-60%, which greatly shortens the customer's project preparation cycle and helps customers put into production and operation quickly. We provide one-stop full-chain services from "design - prefabrication - transportation - installation - commissioning - after-sales".

After Sales Service

We attach great importance to after-sales service, and are committed to solving all problems for customers in the whole process after project delivery. We provide two core installation and guidance services: online guidance and on-site installation, and match a full set of after-sales support to ensure the stable operation of your steel structure workshop and storage space. If you haven't got any drawings, we can do professional structural design & detailed quotation for you.Just share us the following basic information:
