We are a high‑tech enterprise integrating R&D, structural design, steel fabrication, component manufacturing and independent quality testing. We produce light‑steel, heavy‑steel, portal‑frame and space truss steel structures as well as full sets of building envelope products.
Our factory covers 200,000 ㎡, equipped with 8 advanced light‑heavy‑steel production lines with annual output capacity up to 160,000 tons steel components, plus 2 production lines for FK pre‑fabricated exterior wall panels with 400,000 ㎡ annual capacity.
We hold Grade‑1 qualification for steel‑structure manufacturing & contracting. Our titles include National Prefabricated‑Building Industrial Base, National High‑Tech Enterprise, Shandong Provincial “Specialized & Sophisticated” SME and Shandong “Hidden Champion” enterprise. We operate a Shandong‑provincial‑level steel‑structure system integration engineering laboratory and post‑doctoral innovation workstation.
We have 136 professional engineers & technicians, including Grade‑1 registered structural engineers and constructors. We cooperate with well‑known universities, own more than 40 prefabrication‑related patents and have compiled multiple local provincial standards for prefabricated steel‑structure buildings.
We have built provincial enterprise technology center, steel‑structure system integration engineering laboratory and post‑doctoral innovation workstation. Cooperate with domestic top universities; own 2 invention patents, more than 40 utility‑model patents and 6 software copyrights. We have compiled Shandong provincial technical specifications for special‑shaped concrete‑filled steel‑tube column systems, filling industry technical blanks in China.
200,000㎡ modern production base; 8 production lines for light‑steel & heavy‑steel members; 2 special lines for FK precast exterior enclosure panels. Large‑scale production supports both domestic large‑scale projects and overseas export bulk orders.
Our affiliate Deyu Testing Institute holds official CMA measurement certification. We can carry out full testing for construction materials, steel‑member welding quality, wall‑panel physical indexes, building energy‑saving performance and main‑structure safety performance. All products will pass inspection before delivery to clients.
Our team gathers 136 professional technical personnel including Grade‑1 registered structural engineers, registered constructors, cost engineers and safety engineers. We also hire well‑known domestic academicians and experts as long‑term technical consultants for our projects and product development.
Custom heavy‑duty steel frame workshops and warehouses, compatible with overhead cranes. Suitable for manufacturing plants, logistics storage and large‑span industrial facilities. We provide full‑set service including design, fabrication and export packaging.
Prefabricated multi‑storey steel‑frame construction with patented special‑shaped concrete‑filled steel‑tube columns. Excellent grade‑8 seismic performance, widely used for hospitals, schools, office buildings and residential apartments.
FK integrated thermal‑decorative wall panels, ALC lightweight wall panels and modular container houses. Fast installation, fire‑proof and sound‑insulated, ideal for site camps, public projects and residential buildings.
Competitive price does not mean low quality. Defeng delivered reliable steel structures adapted to our local hot climate. We will continue to place repeat orders for our upcoming factory expansion projects.
We cooperated with Defeng Steel Structure for our multi‑bay industrial workshop project. Their detailed design drawings, strict production quality and seaworthy export packaging saved us a lot of on‑site troubles. We are satisfied with the overall cooperation.
