Steel gratings and walkways in an industrial plant

Metalwork for industrial plants: gratings, walkways, frames and pipe supports.

Piping needs supports, plants need access. We design and fabricate made-to-measure metal elements in steel, stainless steel and aluminium that secure and structure your plant. From a single source, together with the industrial piping.

What we fabricate

01

Pipe supports, anchor points and sliding supports

matched to the expansion and load of your lines.

02

Walkways, platforms and stairs

with gratings and railings, for safe access to valves and measuring points.

03

Frames and racks

for pumps, heat exchangers, filters and control cabinets.

04

Stainless steel work tables and equipment

for pharma, laboratory and food areas.

05

Aluminium structures and piping

where weight matters or corrosion is to be avoided without coating.

FAQ

Frequently asked questions

Do you also do metalwork without a piping order?

Yes. We also fabricate pipe supports, walkways, frames and stainless steel tables as a stand-alone order for industrial companies. It is particularly economical when metalwork and piping work are carried out in the same shutdown.

Do you work with aluminium?

Yes. We weld aluminium by the TIG and MIG processes and use it to fabricate structures and piping where low weight or corrosion resistance without coating is required.

Do you also build railings and stairs for residential buildings?

Not for private individuals. For architects, construction companies and public bodies we fabricate metal structures on request; industrial plants remain our main focus.
