Hebei Hongxiang Construction Engineering Materials Co., Ltd., established in 2014, boasts an annual production capacity of 100,000 tons of formwork and scaffolding tubing. Strictly adhering to the national standard JGJ166-2016 for cup-lock scaffolding, the company has independently developed standardized Ledger for Cup-lock Scaffolding.
As the core horizontal force-transfer component of the cup-lock scaffolding system, it plays a crucial role in lateral constraint of the uprights, distributing vertical loads, and constructing stable grid units. It is suitable for all scenarios including full-span high formwork, double-row scaffolding for exterior walls, tunnel support, cast-in-place bridge construction, and main building construction.
Features of Ledger for Cup-lock Scaffolding：
First, boltless self-locking joints. Unlike traditional coupler horizontal bars that require numerous bolts for fastening, Hongxiang cup-lock horizontal bars achieve mechanical self-locking through the rotation and compression of the cup-lock cover.
Only a hand hammer is needed throughout the erection process, eliminating the risk of bolt loss, stripping, or inadequate tightening that could cause lateral displacement of the scaffolding. The overall anti-slip bearing capacity of the joints far exceeds the national standard limit, resulting in zero rejections due to structural defects during special inspections by supervisors.
Second, standardized modularity and universality. A unified 0.6m basic module length ensures compatibility across the entire 48 series of cup-lock uprights. Crossbars from different projects can be directly reused across construction sites without sorting or categorizing, maximizing component interchangeability and avoiding waste from non-standard components. The lightweight crossbars allow for easy handling of multiple units by a single person, eliminating reliance on heavy lifting, and offering significant advantages in confined indoor work areas.
Third, all-condition corrosion resistance. A 70μm thick hot-dip galvanized layer covers all contact surfaces of the components, eliminating blind spots in welded joints. Even after over ten years of outdoor use, rust penetration and weld corrosion cracking will not occur. It maintains structural strength even in the confined, humid spaces of underground water purification plants and tunnels. The entire system has been recognized as a green product for formwork and scaffolding, and passed the civilized construction site assessment on the first attempt.
Fourth, automated and unified quality control. CNC pipe cutting, automatic welding, and a closed-loop galvanizing production line are all operated by specialized machines. The wall thickness, plug size, plating thickness, and welding strength of crossbars in the same batch are highly uniform.
Finished products are printed with factory markings and specifications, and each batch comes with a third-party mechanical testing report. All indicators meet standards on the first attempt during on-site re-inspection.
Core Advantages of Ledger for Cup-lock Scaffolding
Structural Safety Advantage： Crossbars and uprights form a rigid grid frame, which, combined with vertical diagonal braces, forms a triangular stabilizing unit. This effectively constrains lateral deformation of the uprights, significantly reducing the risk of overturning and slippage of high-rise formwork and scaffolding. For ultra-high full-span scaffolding exceeding 8m, the overall critical load for instability is increased by more than 20% compared to ordinary non-standard crossbars after denser deployment.
Construction Efficiency Advantage： Single-span crossbar insertion and locking takes only a few seconds. The erection and dismantling speed is 2-3 times faster than traditional coupler crossbars, significantly reducing labor input and shortening the construction period for main formwork and external wall protection, avoiding losses due to delays. The ground clearance of the sweeping rods can be precisely controlled within the standard 550mm, and the standardized structure requires no additional reinforcement.
Comprehensive Adaptability Advantages： Suitable for various construction scenarios including residential buildings, municipal bridges, pumped storage systems, subway tunnels, and overseas factories. It can flexibly adapt to both heavy-duty multi-span dense layouts and light-duty sparse setups. The complete set of crossbars can be supplied as a complete package with cup-lock uprights, adjustable upper and lower supports, and steel footboards, providing a one-stop solution for the entire formwork system.
Compliance and Acceptance Advantages： Complete material certificates, three-system certification, AAA credit enterprise certificate, and industry-recommended product qualifications. High-support formwork expert review and complete site safety inspection data ensure no issues of material parameters failing to meet standards and requiring rework.
