Modules set on steel construction
- flexibility in design of shape and details
- reduction of project completion time
- no restrictions in choice of finishing layers: glass, HPL, PVC, ceramic tiles, decorative stones, GRP panels with stone imitation, tiles, etc.
- inflexibility in construction
- no need of additional support for plasterboards
- an alternative for GRP construction that eliminates its main disadvantages (necessity of making expensive and time consuming forms and their limpness)
- steel construction covered with PVC/HPL retains main advantages of GRP cabin: easy maintenance and refractoriness of PVC/HPL boards- that is main benefit in terms of restrictive European fire regulations.
- Steel construction covered with gypsum-fibreboards of 2-3mm GRP. That solution is a compromise between inflexibility of steel construction and easy maintenance of GRP. It does not require use of forms and allows fast completion of any project regardless of quantity of ordered cabins.
Main frame of module is made of skeleton steel structure.
Bottom of the cabin is usually made of flat steel sheets(2,5mm thickness) supported by c-rails or square pipes arranged in a shape of grate .
Most common solutions for roof structure depending on its span are:
- Sandwich panel- made of coated steel (0,70mm),with inserts of polystyrene and galvanised steel (0,50mm grade DX51D Z200)
- Roof’s grate made of steel profile, sheathing made of double plasterboard.
Grade of used steel is S235 (in accordance with EN 10025:2002)
Profiles are welded together using electric, arc and consumable electrode with argon insert (MIG) method. Butt weld thickness usually equals 0,6-0,7 of the thinnest welded piece.
Quality of butt weld and construction is checked visually (VT). Construction is protected with layer of paint applied electrostatically.
Skeleton steel construction is covered with
- Gypsum-fibreboards panels are used as base for finishing layers-most often ceramic tiles, tempered glass. Panels are attached with screws in the way prescribed by their producer.
- PVC/HPL panels- spot glued with polyurethane adhesive
- GRP panels glued to gypsum-fibreboards to imitate ceramic tiles.
Additional sheathing provides reinforcement of steel profiles creating construction that is resistant to deformities.
Above solutions have been successfully used by Domczar for years and they have proven themselves as durable and reliable. Bathroom modules are self-supporting structures that do not allow additional load apart from one regulated by norm EN 1991-1-1:2004 for bathrooms.
Wooden structure modules
We can make wooden structure part of a building at customer’s request under condition of providing us with executive project and details of external connections. It allows to save resources and reduces overall cost of a build.
Wooden skeleton structure is additionally covered with:
gypsum-fibreboards used as base for finishing layers- mostly ceramic tiles. Panels are attached with screws in the way prescribed by their producer.
MgO (magnesium) boards serving similar role as one mentioned above (gypsum-fibreboard)
PVC/HPL boards, spot glued with polyurethane adhesive.
Additional board sheathing stiffens wooden rods making whole construction more durable.
In standard, construction is self-supported and does not allow any additional load apart from one regulated by norm (EN 1991-1-1:2004) for bathrooms.
Producing PODs that are able to withstand an additional load range required by customer would have to be prearranged- cabin construction may be made as part of a building.
Modules made of glass reinforced plastic (GRP)
Structure is additionally reinforced with pieces of wooden panels and steel grate on the floor(grade of steel S235 in accordance with EN 1025:2002)
GRP modules produced by us can be divided into two groups:
Laminate construction does not require any additional finishing layers, its internal layer (gelcoat) has decorative purpose.
Class F laminate- no details available about product, in accordance with European norm EN 13501-1.
Laminate can be made according to customer’s specification.
