2 Culverts Modern road construction technologies call for modern solutions. The round pipe type RING and the oval pipe type DROP represent new corrugated steel culverts that can be found in multiple engineering applications across the world. Easy and fast to fabricate, the RING and the DROP keep construction costs down and comply with all environmental regulations and guidelines. A perfect match of superior raw materials and unrivalled workmanship, the RING and DROP corrugated steel culverts deliver a lasting and maintenance-free solution to your construction needs. Raw material Since the service life of any civil engineering project always lies in supreme design and seamless execution, the importance of raw materials applied cannot be emphasized too heavily. Types of steel applied to fabricate the couplers and corrugated pipes RING and DROP. PN-EN 1037:006 "Continuously hot-dip coated strips and sheets of low- carbon steels for cold forming Technical conditions of delivery". PN-EN 1036:006 "Continuously hot-dip coated strip and sheet of structural steels - Technical delivery conditions". Steel type DX51D S50GD Standard PN-EN 1037 PN-EN 1036 Corrosion-resitant coating Corrosion is a recurring phenomenon on many a project, so appropriate coating has been applied to keep the corrosion hazard to a minimum g/m zinc coating on both sides of the sheet, equivalent to 4μm on each side g/m zinc coating both sides, equivalent to 70μm on each side g/m zinc coating both sides, equivalent to 4μm on each side, with an additional 300μm polymer film (Trenchcoat (W-Protect ) on one or both sides steel culverts S Y S T E M fittings accesories

3 The TRENCHCOAT Protective Film is a highly damage-resistant polymeric coating that can resist the adverse impact of all corrosive materials, such as acids, salts and alkalines. Designed to combine the strength of a galvanized sheet with the supreme ductile properties and chemical resistance of the polymer, the TRENCHCOAT film adds another dimension of insulation to the corrugated pipe, irrespective of exposure to the elements. Steel laminated with the TRENCHCOAT Film can be most easily roll-formed and lock-seamed without coating damage and pipe ends are protected with a corrosion-resistant coating. The TRENCHCOAT film is applied once the steel sheet has been galvanized. Pressure and temperature combine to merge the superior chemical properties of the polymer with the mechanical properties of a galvanized sheet.

Types of corrugations in roll- formed, lock-seamed pipes include mm and mm, where the former figure defines the pitch, while the latter the depth of the corrugation.

4 Culvert rigidity Steel sheets that are roll-formed into pipes lock-seam to ensure maximum culvert rigidity. gap gap for the D1 corrugation () the leg length should be minimum 6.5mm while the D3 corrugation () requires minimum 8.0mm leg Bands Where project design calls for longer culvert sections, they can be connected using a variety of special joints. Typ A- flat band with angles Typ B - helically corrugated band with angles Typ C - helically corrugated band with angles and a rod Typ D - corrugated band with angles applied on the reformed pipe end Typ E - semi-corrugated band applied on the reformed pipe end Typ A Typ B Typ C Typ D Typ E D= φ300- φ140 0 D= φ300- φ3600 D= φ300- φ3600 D= φ300- φ3600 D= φ300- φ3600 B ± % B ± % B ± % B ± % B ± % Band width should be maximum 0.4 D, but not less than 300mm, where B is band width, while D is band diameter For any type of band the number of bolts increases proportionally to the band width growth. All bands are made of the same raw material as the pipes they connect. To ensure maximum resistance to corrosion, all welded, ground, bored and cut areas are secured with a corrosion-resistant coating. Band TYPEA, B,C,D, and E can be used to connect type RING pipes Band TYPE B and C can be used to connect type DROP pipes steel fittings accesories S Y S T E M 4
