Technical appendix - Seating

Elegant shapes, modern materials…

The GHM seating line is at the service of city planners who need to offer city-dwellers places to relax or to take a breather... Designs, volutes, curves or stretched geometry, noble materials, cast iron, steel, aluminium, wood, combined shapes and materials give GHM benches and seats the capacity to highlight city environments.  The selection of models offers a wide choice of designs and prices. Compliant with the NFP 99-610 standards, GHM benches provide comfort and safety to both adults and children.

Finishes and colours


All GHM products are carefully prepared before the final coating is applied. Surface preparation: Cast iron: zinc coating (NF EN ISO 2063 standard) / Aluminium: phosphating passivating / Steel: hot dip galvanisation (NF EN ISO 1461), zinc coating (NF EN ISO 2063) / Certified origin timber: varnish sanding, sanding, drying and application of paint or surface treatment. Coating: cast iron, aluminium, steel: application of a polyester thermosetting powder coat in RAL shades. GHM's PIXEON technique copies picture compositions or photos on certain flat elements including the CEANO and CEANA line seats (see relevant section).

Maintenance (NF P 99 - 650 standard)

To keep the products intact even longer, it is recommended to treat damage that has breached the protective coating film. Yearly preventive care is also recommended.

The materials


Manufactured using grey or ductile cast iron, seating frames and legs withstand the test of time.
The certified origin timber selected by GHM meets the most demanding requirements in terms of humidity content and dimensional stability. They are surface treated using a technique approved by the CRITT.
An anti-graffiti coating can be applied as an option.
For its CEANO and CEANA lines, GHM proposes PERMASTEN seats, a material that faithfully imitates wood and is particularly strong.


Depending on the type of installation, several fixing alternatives are available.
