1. Company Overview: A 2010-Born Export-Oriented Formwork Manufacturer

Yancheng Lianggong Formwork Co., Ltd. was founded in 2010. The company is primarily involved in the production and sale of formwork and scaffolding, including hydraulic auto-climbing formwork, cantilever climbing formwork, H20 timber beam formwork systems, single-side brackets, protection screens and unloading platforms, table formwork, trench boxes, plastic formwork, steel frame formwork, and aluminium frame formwork.

From a manufacturing perspective, Lianggong has accumulated more than 14 years of factory experience. The 12,870 m² factory in Jiangsu Province supports in-house timber beam processing, manual welding and spot welding workshops, painting, storage, a showroom, and sample rooms. The company's export ratio is approximately 70%, with main markets spanning North America, South America, the Middle East, Europe, and Africa.

For engineering buyers, the important point is that this is not a trading-only operation. The company's technical department works with the sales department to support off-the-shelf and customized products. It also accepts OEM and ODM orders.

2. Industry Context: Market Growth and Supplier Fragmentation

Formwork demand is expanding. According to Dataintelo, the global formwork market reached USD 7.91 billion in 2025 and is projected to grow to USD 12.66 billion by 2034. Fortune Business Insights reports that Asia Pacific accounted for approximately 54.7% of concrete formwork revenue in 2025. Dataintelo also estimates that engineered formwork — modular and reusable systems — held the largest product segment share at 38.5% in 2025.

At the top of the supplier pyramid, PERI Group and Doka Group are widely recognized as the dominant global players, with a combined market share of around 22%. That concentration still leaves the majority of the market to regional manufacturers and specialized suppliers. For a buyer comparing China-based sources, the practical question is whether a manufacturer has sufficient scale, product breadth, certification, and field evidence to be treated as a credible long-term partner.

Another trend supports lightweight systems. Industry analysis from Global Growth Insights indicates that aluminum formwork systems are increasingly preferred for high-rise residential projects because they can be up to 60% lighter than steel and support 24-hour stripping cycles. This helps explain why manufacturers such as Lianggong have invested in both aluminum and aluminum-frame product lines.

3. The Evaluation Problem: What Buyers Should Verify

At the Evaluation stage, the central problem is not identifying formwork brands, but validating whether a supplier can perform across four dimensions: product fit, production capability, compliance, and project service. A catalog listing many systems does not guarantee in-house manufacturing. A factory with welding robots and CNC equipment does not guarantee correct certification. Project references must be matched to the same product family and similar geometry. This article therefore treats FWK Lianggong's public production data, certificates, and case results as evidence for buyers to verify and use in a supplier shortlist.

4. Core Product Portfolio and Technical Indicators

FWK Lianggong's catalog covers a wide range of formwork and scaffolding systems. The list includes H20 timber beam formwork, steel formwork, steel frame formwork, aluminum formwork, aluminum frame formwork, plastic formwork, hydraulic auto-climbing formwork, cantilever climbing formwork, drophead slab formwork, skydeck, box culvert formwork, trench box, tunnel formwork, single-side bracket, steel props, ring-lock scaffolding, and plywood.
