Best Weight-Strength Ratio Beam

Assemble a Custom Lightweight, High Load-Bearing Beam Suitable for Every Job

What is a SIN Beam?

Zeman developed the SIN beam and the machine to produce it back in 198X to address a need for a lighter structure with the same load-bearing capacity of conventional hot-rolled or built-up steel beams. Our innovation is a precise corrugated web produced by our autonomous welding beam assembler, capable of handling greater loads over incredibly large spans with less material and a low beam height.

Lighter and Stronger Beams, On-Demand

The SIN Beam Machine is a fully automatic production line for producing corrugated web beams. Full work sequences from rollforming the web material, slitting, cutting to length and finally assembling and welding in one step. The web is welded to the flange automatically by up to four welding robots depending on your needs. 

Precision and Speed

Our machine laser scans the web as it is welded to assure the most precise output. Same as all our welding machines, it’s simply the best on the market. The SIN beam line can be used for the production of parallel and tapered beams up to a length of 16m and a width of max. 1500mm.

Built-in Plasma Cutting

Easily program slitting for tapered beams, length cutting and processing circular or rectangular holes into the web plate while the beam is being produced, eliminating a common step in beam production and saving even more time!

Increase Profit on Every Job

You can easily save 30% of your material weight on most projects, reducing material used and production costs. Produce your beams to specification and on-demand for a faster turnaround and higher profit!
