Your Trusted Chinese Steel Building Manufacturer & Export Company
Founded in 1999. Registered capital RMB 100.99 million. 300-mu manufacturing base. 200,000 tons of steel structures per year. We are not a trading company, and we are not just a fabricator. We are a full-industry-chain steel structure building service provider.
Twenty-Five Years of Building What Others Cannot
Jiangsu Permanent Steel Structure Co., Ltd. (hereinafter referred to as "Permanent Steel") was founded in 1999 in Xuzhou, Jiangsu Province. What started as a regional steel structure fabricator has grown into a full-industry-chain, green, prefabricated spatial grid structure and high-end steel structure building service provider, integrating design, manufacturing, construction, and operation & maintenance.
That is a long description, so let us break down what it means in practice. "Full-industry-chain" means we own every phase from structural design to post-construction maintenance. "Green" means our manufacturing processes, material selection and building systems are designed to minimize carbon footprint, certified by national-level green-building standards. "Spatial grid structure" means our specialty is not simple I-beam frames but complex three-dimensional space frames, pipe trusses and prestressed structures that span 100-229 meters without interior columns.
As a steel structure manufacturer from China with a registered capital of RMB 100.99 million, we own a prefabricated component manufacturing base of over 300 mu (approximately 20 hectares). Our 100,000m² of production workshops produce 200,000 tons of grid structures, trusses and steel structures annually. We also construct over 3,000,000m² of steel structures each year.
Nine Structural Technology Systems, Not a Catalog of Beams
Most Chinese steel building manufacturers list their products as categories: H-beams, box columns, trusses. We list ours as technology systems, because each one solves a specific building problem that off-the-shelf solutions cannot.
Long-span Spatial Grid
Bolted-sphere and welded-sphere space frames for 100m+ clear spans.
Beam-string Structure
Prestressed cable-strut systems for 200m+ spans at reduced steel weight.
PEC Integrated Residential
Low-carbon composite columns cutting concrete usage by 40%.
High-rise All-steel
Fully prefabricated steel buildings up to 180m tall.
Industrial Building
Workshops, warehouses and plants with clear-span frames.
Light Steel, Modular, BIPV, Bridge
Ultra-light steel framing, modular buildings, solar-generating roofing and prefabricated steel bridges.
Six Special-Grade Licenses — The Highest Portfolio in the Industry
Qualifications are not trophies. They are legal authorizations that determine what your contractor is allowed to build. Here are the six we hold.
Building Construction General Contracting
The highest general contracting license for building construction in China. Authorizes us to act as the primary contractor for projects of any scale.
Steel Structure Specialized Contracting
The highest specialized contracting license for steel structure engineering. Required for complex steel projects including high-rise and large-span structures.
Light Steel Structure Special Design
The highest design qualification for light steel structures. One of only a handful of companies in China authorized to design, not just fabricate, light steel systems.
Steel Structure Manufacturing
Special-Class manufacturing qualification. The highest manufacturing license, certifying our capability to produce steel structures for the most demanding project categories.

100+ Patents. Joint Lab with Shanghai Jiao Tong University.
Steel structure manufacturing is not static. Codes evolve, materials advance, and building forms grow more complex. Our R&D investment ensures our engineering does not fall behind.
R&D Engineers
Over 60% hold senior professional titles
Patented Technologies
Covering design, fabrication and construction methods
Publications & Standards
Industry-contributing research and national/co-authored standards
In 2023, we established the Research Center for Intelligent Construction of Spatial Steel Structures jointly with the School of Naval Architecture, Ocean and Civil Engineering at Shanghai Jiao Tong University. This is not a sponsorship arrangement; it is a working research partnership focused on the next generation of intelligent design, manufacturing and construction technologies for spatial steel structures.
Recognized Where It Counts
These awards are granted by independent government bodies and industry associations after on-site audits — not self-declarations.
Luban Prize

A China Steel Structure Export Company Built for International Standards
As a steel structure manufacturer from China serving global markets, we understand that international clients need more than a product. They need a partner who speaks their engineering language.
Projects Across Four Continents
- Antarctica — Ross Sea New Station, China's first new-era year-round research station, engineered for extreme cold and wind
- Africa — Republic of the Congo Airport steel structure and enclosure works, 5,200m², 1,200 tons, max span 43m
- South Asia — Pakistan Tarbela and Karot Hydropower stations, curved H-steel structures with anti-corrosion standards exceeding domestic norms
- Southeast Asia — Indonesia Jinrui New Energy coke yard, H-steel truss structures with concrete roof
What International Clients Can Expect
We work with international codes and standards, not just Chinese GB. Our engineering team can deliver designs compliant with Eurocode, AISC and other regional standards. Our export logistics team handles container loading, documentation and customs clearance for steel structure shipments to any port worldwide.
Our WhatsApp line (+86 18621689980) and email (market@permanentsteelstructure.com) are staffed by English-speaking engineers, not just sales agents. When you ask a technical question, you get a technical answer.
This is what it means to work with a China steel structure export company, not a domestic supplier that occasionally accepts foreign orders.
Sustainability Is an Engineering Discipline
Steel is the world's most recycled material. See the numbers behind our environmental management, the carbon case for steel versus concrete, and how our systems support LEED and BREEAM credits.
From ISO 14001-certified plants to 90%+ steel recyclability and BIPV-ready roofing systems, our sustainability commitments are documented, measurable and audit-ready.
- Embodied carbon: steel frames typically cut embodied carbon 20-35% versus reinforced concrete
- Recyclability: structural steel recovery above 90% at end of life
- Green manufacturing: ISO 14001 environmental management, intelligent lean production lines
- Green building: envelope and BIPV systems mapped to LEED v4 / BREEAM credits
