    Advantages

    1. Core load-bearing capacity and safety advantages

    As a key connecting component of the scaffolding system, our beam clamps (also known as Gravlock or Girder Coupler) are specially designed for the safe connection of I-beams and steel pipes. Their core value lies in providing extremely high load-bearing capacity and structural stability. It ensures the integrity and safety of the entire support system and is an indispensable component for bearing the key loads of the project and ensuring construction safety.

    2. Outstanding materials and manufacturing quality

    We insist that quality stems from materials. All beam clamps are made of high-quality, high-purity steel to ensure that the products have outstanding strength, durability and anti-deformation ability. Each product can stand the long-term test of harsh working conditions, ensuring its promise of "greater durability" from the source.

    3. Certified by authoritative international standards

    The quality of our products not only remains at the level of commitment, but has also passed the strict testing of the authoritative third-party institution SGS, fully meeting and exceeding multiple international mainstream standards such AS BS 1139 (British standard), EN 74 (European standard), and AS/NZS 1576 (Australian and New Zealand standard).
