Hebei Hongxiang Construction Engineering Materials Co., Ltd. has been deeply involved in formwork manufacturing for over a decade. They have independently developed a standardized Ledger for Ringlock Scaffolding, a core horizontal force-transfer component in the socket-type disc-lock scaffolding system. Strictly adhering to JGJ/T231 standards, the Ledger utilizes original Q235 low-carbon alloy steel pipes, over 20 fully automated precision machining processes, and a 70μm standard internal and external hot-dip galvanized layer. From raw material control, joint welding, and anti-corrosion treatment to factory mechanical testing, a complete quality control system has been established. This system solves common safety hazards on construction sites such as weld cracking, joint loosening, rust thinning, large dimensional deviations, and node force transmission failure in traditional crossbars. It is widely applicable to various construction scenarios including full-span formwork for residential buildings, municipal viaducts, subway tunnels, pumped storage power stations, large public buildings, and overseas infrastructure projects. Established in 2014, the company covers an area of over 30 acres and produces over 100,000 tons of scaffolding pipes annually. It holds ISO9001 quality management system certification, ISO14001 environmental management system certification, and ISO45001 occupational health and safety management system certification. It is a long-term supplier to central state-owned enterprises such as China Railway, China Communications Construction Company, and China Railway Construction Corporation. Its products have been recognized as key recommended products for national construction projects and are recognized as a leading brand in disc-lock scaffolding. The stability, load-bearing capacity, and long-term durability of its crossbars have been verified in hundreds of national key projects.
This series of Ledger for Ringlock Scaffolding uses Φ48 low-carbon alloy steel pipes with a standard wall thickness of 2.75mm. The base material is selected from original Q235 hot-rolled strip steel from a major manufacturer. Material quality certificates are issued for each batch upon arrival at the factory. Each batch undergoes tensile, bending, and non-destructive testing for wall thickness, eliminating defective materials with inclusions, cracks, and excessive wall thickness tolerances to prevent bending and deformation of the members caused by inferior raw materials. The crossbars cover a full range of modular lengths： 60cm, 90cm, 120cm, 150cm, 200cm, 250cm, and 300cm. They precisely match the octagonal connecting plates spaced 0.5m apart on the uprights, achieving standardized 300mm modular assembly. No on-site cutting or grinding modifications are required, making them perfectly adaptable to various work conditions, including single-row external scaffolding, double-row operating scaffolding, indoor high-formwork, and bridge cast-in-place support. The integrated cast steel couplings at both ends of the crossbars are machined with a fully automated circumferential welding machine, eliminating defects such as incomplete welds, slag inclusions, and porosity caused by manual spot welding. The welds are full and uniform, and each crossbar is individually inspected for hidden welding damage. The coupling's curvature conforms to the outer wall of the upright steel pipe, and after insertion into a small hole in the disc, it is self-locking with a wedge-shaped pin. The pin's pull-out resistance is consistently above 3kN. This three-point load-bearing structure evenly transmits horizontal loads, preventing localized stress concentration and cracking at joints, ensuring the overall rigidity of the scaffold from the structural foundation.
The entire production process utilizes automated specialized machinery, minimizing human error. Each crossbar boasts highly uniform dimensions, weight, plating, and welding quality, ensuring maximum interchangeability. CNC pipe-cutting equipment precisely cuts the crossbars to length, resulting in clean, burr-free cuts. End-joint positioning fixtures secure the crossbars, ensuring zero welding position deviation. Formed crossbars are uniformly fed into a closed galvanizing production line, with crossbars of varying lengths immersed in the plating process to prevent incomplete plating on the inner wall of the steel pipe or at joint seams. Finished crossbars are uniformly printed with factory markings, specifications, and material identification. Each batch comes with complete bending and shear strength test reports. Supervisors conduct on-site re-inspections to ensure that wall thickness, zinc coating, and joint load-bearing capacity all meet standards, eliminating the need for additional rework and testing. This standardized mass production model eliminates the need for frequent mold changes on the production line, maintaining complete consistency in parameters, plating, and welding quality even during peak seasons with large-volume deliveries, preventing inconsistencies in crossbar performance within the same batch.
Hongxiang Ledger for Ringlock Scaffolding is a key component in forming a geometrically invariant and stable scaffolding system. The bottom horizontal bar, acting as a ground-level bracing bar, has its ground clearance strictly controlled within 550mm. Multiple layers of horizontal bars connect to the uprights in a grid structure, which, combined with vertical diagonal braces, forms a triangular stable load-bearing unit, significantly reducing the risk of scaffolding slippage, overturning, and lateral instability. This horizontal bar comes with the company's complete set of 60/48 series disc-lock uprights, diagonal braces, adjustable screws, and steel footplates. All assembly and disassembly operations can be completed with just a hand hammer, eliminating the need for wrenches, clips, and other loose accessories. Construction efficiency is increased by more than 60% compared to traditional coupler scaffolding, effectively shortening project timelines.
Our scaffolding has been successfully implemented in major projects such as the Shenzhen Honghu Underground Water Purification Plant, Guangzhou Metro Line 12, Zhejiang University's National Laboratory for Supergravity, Beijing's Sub-center Integrated Transportation Hub, Shaanxi Zhen'an Pumped Storage Power Station, and the Ivory Coast Overseas Roundabout Project.
It has withstood the test of multiple working conditions, including underground confined and humid spaces, high-formwork support for large-span cast-in-place beams, long-distance municipal bridges, and highly corrosive overseas environments.
Our company has a professional technical team that can provide guidance on crossbar layout and erection specifications based on construction drawings, and simultaneously provide a complete set of qualification certificates, material certificates, and test reports, offering a one-stop solution for procurement, testing, and on-site technical support.
Adhering to the core business philosophy of "Today's quality, tomorrow's market," Hongxiang uses precision-manufactured, long-lasting, corrosion-resistant, and high-strength standardized disc-lock crossbars to build a solid horizontal load-bearing safety line for infrastructure projects both domestically and internationally.
