Engineered for high structural stability, rapid assembly, and high resistance to tropical coastal humidity in Sri Lankan megaprojects.
The construction and infrastructure landscape of Sri Lanka is undergoing a strategic renaissance. With landmark projects such as the Colombo Port City Economic Zone, maritime expansions at the Hambantota International Port, coastal expressway extensions, and luxury hospitality high-rises along the Western and Southern coastlines, the demand for certified, safety-critical access hardware has reached unprecedented levels.
Scaffolding clamps—commonly known across South Asian job sites as couplers, right-angle clamps, swivel couplers, putlogs, and sleeve couplers—form the foundational joints of tubular scaffolding networks. In tropical and maritime environments like Sri Lanka, standard couplers often succumb to aggressive salt-fog corrosion, mechanical fatigue, and thread jamming. Tianjin Jinke Construction delivers export-grade, CE Certified (EN74 Class A & B / BS1139) drop-forged and pressed steel clamps designed specifically to withstand harsh marine ambient conditions while providing uncompromised slip resistance and load capacities.
Our direct export pipeline to the Port of Colombo (LKCMB) ensures rapid container turnaround, complete customs documentation, Mill Test Certificates (MTC), and verified conformity certificates required by Sri Lankan regulatory authorities (such as CIDA - Construction Industry Development Authority).
| Clamp Type | Standard | Slip Load |
|---|---|---|
| Double Right Angle (Fixed) | EN74 Class B / BS1139 | ≥ 15.0 kN |
| Swivel Coupler (360°) | EN74 Class A / BS1139 | ≥ 10.0 kN |
| Sleeve / Joint Coupler | EN74 Class B | ≥ 6.0 kN (Tension) |
| Board Retaining (BRC) | BS1139 / AS1576 | Secure Clamping |
Established in 1998, Tianjin Jinke Construction is a professional scaffolding manufacturer and solution provider based in Tianjin, China. With 28 years of manufacturing experience, we have grown from a local factory into a trusted international supplier. Since 2012, we have been engaged in export business and now have more than 14 years of experience serving global customers. We focus on safe, reliable and high-quality scaffolding products to support construction projects around the world, including major commercial developments and industrial complexes across Sri Lanka.
Sri Lanka's equatorial climate delivers relentless rainfall, high temperatures, and intense saline air that aggressively corrode sub-standard steel hardware. Discover how our engineered clamps provide maximum safety.
Manufactured using high-tonnage friction forging presses. The refined internal grain structure of our carbon steel eliminates internal air pockets, micro-fractures, and structural vulnerabilities common in low-cost cast iron couplers.
Offered in Hot-Dip Galvanized (HDG, ASTM A153 / EN ISO 1461) and Heavy Electro-Galvanized finishes with passivated protective zinc coating layers (>15μm - 60μm), preventing salt-spray oxidation across waterfront job sites.
Equipped with cold-forged Grade 8.8 high-tensile steel T-bolts and heavy hex flange nuts (21mm / 22mm / 23mm socket sizes). Engineered torque resistance (54 Nm to 65 Nm) guarantees secure pipe clamping without stripping threads.
Our story began in 1998 with a simple goal: to provide strong and safe scaffolding products. In the early years, we focused on improving production technology and quality control. As we grew, we invested in modern workshops and automated equipment to meet higher industry standards. In 2012, we started our international business and quickly earned recognition from overseas buyers for stable quality and on-time delivery. Over the years, we have kept improving our products and services, attending global exhibitions and building long-term partnerships with customers from different countries. Today, we remain committed to our original spirit: professionalism, quality and trust.
Empowering local civil engineering contractors, government infrastructure projects, and commercial builders with dependable high-load couplers.
Widely deployed across skyscraper facade glazing, curtain wall maintenance, and structural shoring frameworks in the Colombo 01, 02, and 03 financial zones. Guarantees zero-deflection under strong Indian Ocean wind shear loads.
Essential for dockside crane maintenance, breakwater repair platforms, container terminal facility expansions, and shipyard scaffolding towers where high humidity and salt exposure require anti-corrosive HDG couplers.
Supplying power plants such as Norochcholai, Kerawalapitiya, and central highland hydropower dams with heavy-duty cuplock, ringlock, and tube-and-clamp systems for scheduled boiler overhauls and penstock maintenance.
Critical structural components for heavy falsework shoring during bridge pier casting, flyover beam erection, and viaduct construction on the Central Expressway (CEP) and Southern Expressway networks.
Used by industrial contractors in Katunayake and Biyagama EPZ for fast structural framing, roofing truss installations, industrial MEP ducting, and factory retrofitting works.
Non-invasive, flexible tube-and-clamp access scaffolding utilized in preserving cultural heritage monuments in Galle Fort, Kandy, and erecting eco-tourism retreats along Ella and Weligama cliffs.
