FAQs

Find the most sought-after GLP beam information here. Making it the perfect resource for all your technical inquiries.

What are the advantages of using corrugated plates over traditional flat steel plates?

Corrugated plates offer a significantly higher strength-to-weight ratio, allowing for lighter constructions without compromising structural integrity. They also enable longer spans and reduce the need for additional reinforcements.

Can corrugated plates be customized to fit specific project requirements?

Yes. Our patented production process allows us to produce plates of unlimited length and in various dimensions, tailored to the exact needs of your construction project.

What types of projects are corrugated plates and GLP beams suitable for?

Our solutions are ideal for industrial buildings, offshore constructions, bridges, floor systems, and long-span structural applications that require both strength and material efficiency.

How is quality ensured during production and delivery?

All our products undergo rigorous quality checks throughout the production process. We comply with European standards and offer optional surface treatments, such as hot-dip galvanizing, for additional durability.

What is the maximum transport length for corrugated plates and beams?

Due to transportation regulations, the maximum transportable length is 18 meters. For longer constructions, on-site assembly or segment connection is advised.
