Underground structures face specific constraints: constant damp, corrosive atmospheres, heavy traffic, fire safety requirements, water drainage and safe access to equipment.

To address these challenges, JK Technic offers a complete range of solutions for building:

- technical walkways; 
- access walkways; 
- maintenance platforms; 
- staircases; 
- circulation areas; 
- perimeter protection. 

Every project gets a solution matched to its mechanical, environmental and regulatory constraints.

Sturdy and long-lasting, metal grating is the benchmark solution for structures requiring high mechanical strength.

Available in galvanised steel, stainless steel or aluminium, it can be used to build walkways, platforms, footbridges or staircases while providing:

- excellent load capacity; 
- efficient drainage of water and dirt; 
- natural ventilation of structures;
- a long service life. 

JK Technic offers several manufacturing technologies, in particular press-welded and press-locked grating, to meet the needs of each project.

Where environments are particularly damp or corrosive, FRP grating is an especially effective solution.

Made from glass-fibre reinforced resin, it offers many advantages:

- excellent corrosion resistance; 
- resistance to weather and UV; 
- no electrical conductivity; 
- low thermal conductivity; 
- M1/F1 fire rating available depending on the reference; 
- anti-slip surface up to R13; 
- easy to cut and install on site. 

Its light weight also makes installation and maintenance easier. 

 

Beyond grating, JK Technic offers a complete range of products to make infrastructure safe:

FRP railings
Corrosion resistant and requiring no particular upkeep, they provide lasting protection for platforms, walkways and technical areas. 

Stair treads
Available in steel, stainless steel, aluminium or FRP, they guarantee safety, grip and durability. 

Safety grids
Their various surfaces improve grip while allowing water to drain and air and light to pass through.
