wellplatten

Wellplatten are corrugated panels used for roofing and wall cladding in buildings such as barns, industrial sheds, carports, and warehouses. They are characterized by a wavy or trapezoidal profile that increases stiffness and allows for quick installation. The term covers a range of materials, including asbestos cement sheets (historically common), metal sheets (steel or aluminum), and modern plastics or fiber-reinforced polymers.

Historically, wellplatten gained popularity in the 20th century due to their light weight, durability, and ease of handling. Asbestos-containing versions were widely used in older constructions but have since declined due to health risks. In contemporary use, wellplatten are often made from metal or plastic materials, including polycarbonate and fiberglass-reinforced variants, which provide good weather resistance and daylight transmission in greenhouse applications.

Advantages of wellplatten include rapid installation, relatively low cost, good weather resistance, and versatility in both roofs and walls. Limitations depend on material: asbestos-containing sheets pose serious health and environmental risks and require professional removal; metal sheets can be prone to corrosion in aggressive environments and may require coatings or paints; plastic variants can yellow or degrade under UV exposure and may have lower fire resistance. Sealing at overlaps and proper fasteners are essential to prevent leaks.

Regulation and safety considerations emphasize avoiding asbestos-containing products and handling any legacy materials according to local waste and hazard guidelines. Maintenance typically involves inspecting for cracks, corrosion, or leaks, cleaning debris, and replacing damaged sections. Wellplatten remain a common option where their profile and installation advantages meet project needs, though material choices have shifted toward safer and longer-lasting alternatives.
