POLES, Wood: We use laminated scandinavian machine strength graded pine wood to avoid cracks and ensure the structural strength of supports. The wood is treated in an autoclave (risk class IV). PANELS, HDPE: High-density polyethylene characterised by its resistance to chemical abrasives and unaffected by corrosion as it is a polymer. Due to its light, elastic nature, it offers high resistance to impact, making it very difficult to break. The colour uniformity of the whole structure grants a continuous and homogenous finish. Its synthetic base prevents the appearance of bacteria, fungus and lichen. Plastic parts: injected HDPE, injected PP, injected PEAD and injected LDPE. Metallic Parts: different metal compounds used which are resistant to corrosion like as stainless steel and hot-galvanised steel and powder coating. Pipes made of stainless Steel AISI-304. Fixings: Steel conforming to 8.8 DIN267, AISI-304 or AISI-316.
