PROTECTIVE PANEL
The hood is sized 93,5Χ97,5Χ7 cm. And it consists of :
2 pcs of wood dimensioned 4Χ7Χ96 cm.
1 pc of plywood dimensioned 85,5Χ90Χ2 cm.
Between the two wooden pillars dimensioned 4Χ7Χ96 cm., at a height of 8 cm from their base, is placed the ply wood. The protective panel is place on the free from activities side of the tower to protect kids from falling, in conformity with the ΕΝ 1176.
PLYWOOD
The plywood-made parts, which are required for our structures are at least 20 mm thick and are made of wood sheets each 1,5 mm thick, being welded between each other, by way of thermo-welding process under pressure, using resins of phenol base, non-toxic. They are dyed with water-dissoluble paints, in which no sealing compounds have been added, nor any diluting items or dyes, which contain lead, chrome, cadmium or other heavy duty metals. The paints also offer high resistance under adverse weather conditions.
The above sheets of plywood are in conformity with standards ΕΝ 314-2.
The quality of the plywood is such that no further processing is required prior to the dyeing process, such as application of putty.
PLASTIC ELEMENTS
The plastic elements that are required for the manufacture of equipment are highly resistant to the ultra violet radiation and in unfavourable weather conditions. The preferred materials are those which can be recycled such as the polyethylene (ΡΕ) or the polypropylene (ΡΡ). In particular, all the bolts, which stand out of the equipment by more than 5 mm, are covered with plastic plugs of propylene (ΡΡ). Also, they are harmless for the safety and the health of the children.
METAL ELEMENTS
The metal elements that are used for the manufacture of equipment (screws, contacts etc) are manufactured from thermo-galvanised steel (with zinc), electro-galvanised, in which the surface has been previously prepared with sandblast or stainless (stainless steel). The dimensions and the cross sections of the metallic elements are sufficient to accommodate (with the suitable safety coefficient) the loads for which they have been studied to resist corrosion and adverse weather conditions.
PAINTS
The varnishes and the paints with which the wooden parts are protected, have been specifically studied for the climatic conditions of our country (temperature changes, open or closed spaces etc), are entirely harmless for the users (they contain no lead, chrome or cadmium or any other heavy metals) and they give a high resistance in our structures.
EMBEDDING
The embedding of the equipments calls for the following procedure:
At this point in which the pillar is to be fitted, a pit is opened up in the form of truncated cone, 80cm deep approximately, and 60cm in diameter. Afterwards, after the pillar is fitted inside it, the pit is filled up with concrete until it reaches 20cm. from the level of the ground, where it is covered with the ground.
Only the embedding irons are embedded in the ground, which keep down every pillar at a distance of at least 10 cm. from the ground, in order to prevent the corrosion of the wood due the humidity of the ground.
All the procedures of the production works for processing the raw materials are carried out in conformity with
· The standards ΕΝ 1176 1-6,
· the system of quality ISO 9001 : 2000
· and system of environmental management ISO 14001 : 2004
