Lindapter: Inventor of Girder Clamps and Pioneer of Steel Connections

Lindapter transformed steel construction in the 1930s by inventing the first Girder Clamps — eliminating the need for drilling and welding. This breakthrough innovation set the standard for secure, adjustable, and cost-effective steel connections.

Today, Lindapter remains the global leader in clamping technology, delivering solutions that meet New Zealand’s stringent building requirements for strength, compliance, and reliability. Backed by ICC-ES seismic certification, Lindapter Girder Clamps are engineered for tough conditions, providing proven performance supported by decades of expertise

Why Use Girder Clamps?

Versatile Application for Open Steel Sections: Lindapter's Girder Clamps (Types AF, B, D2) securely connect I-beams, channels, and angles without on-site modifications, ideal for beam-to-beam joins in bridges and warehouses.
Full Adjustability and Quick Alignment: Adjustable for parallel and tapered flanges (up to 5°), they enable fast setup in misaligned frameworks.
Efficient Installation and Cost Savings: Tighten with a standard wrench in minutes, cutting time by up to 50% versus welding and reducing labour/equipment costs on sites.
High-Strength and Durable Design: Made from high-tensile steel with galvanised options for corrosion resistance, delivering up to 100kN loads in tension and shear for harsh conditions.
Seismic Compliance and Safety: Meet NZ Building Code for ductility in quake zones; no-hot-work minimises risks under Health and Safety Act, with high slip resistance for transport and multi-storey uses.

What is ICC?

ICC stands for the International Code Council, the organization behind the International Building Code (IBC)—a globally recognized set of safety and performance standards for construction.
When a product is ICC-ES approved, it means it has passed rigorous independent testing and evaluation to ensure compliance with these codes, giving engineers, designers, and inspectors confidence in its structural integrity and safety.

Lindapter offers the world’s first structural steel clamping systems approved for use in all Seismic Design Categories (A–F) and fully compliant with the IBC. This is a major advantage for projects in earthquake-prone regions or those requiring strict code compliance. For more information on ICC, click here.

Case Study: Story Bridge Adventure Climb

Product used: Girder Clamps

Lindapter's solutions have contributed to iconic projects worldwide, including Australia. The case study below show how Girder Clamps deliver in high-stakes environments.

In Brisbane, the Story Bridge Adventure Climb project needed to bridge steel girders for elevated walkways without invasive fixes. Lindapter's Girder Clamps were the hero, providing adjustable, high-strength connections that allowed for quick on-site tweaks and zero damage to existing structures.

This pedestrian-friendly upgrade highlights how girder clamps excel in public infrastructure. No welding sparks, no downtime: just reliable, cost-effective steel joins that keep projects moving.
