How long has corrugated steel culvert been used as drainage and construction tools? The original concept of corrugated steel pipe was introduced by ARMCO in the USA in 1896 with the first been manufactured in Crawfordsville, Indiana. The first corrugated steel culvert in the UK was installed in 1913. Since then, it has become a major drainage material and construction tool throughout the world and won the confidence of and found acceptance by highway and drainage engineers in central and local government, consulting civil engineers and architects. Do ASSET’s products come as one piece? No. ASSET’s product is a construction system based around curved, corrugated, galvanised steel sheets which are bolted together on site to form durable structures, or part structures, of variable profile that can be deployed in a variety of construction roles How are MULTIPLATE structures shipped? Plates for MULTIPLATE structures are shipped nested in bundles complete with all bolts and nuts necessary for assembly. Included with the shipment are detailed assembly instructions. Bundles are normally 2 tons maximum weight for ease of handling. How long would it take from placing an order to delivery? For MULTIPLATE and Superspan, the normal lead time to delivery is around 4-6 weeks. And for Stren-Cor and Tunnel Liner, it would take around 10-12 weeks to deliver.
