Hengshui Zhanhe Engineering Rubber Co., Ltd. supplies galvanized corrugated steel culvert and related engineering rubber products to contractors, distributors and infrastructure projects worldwide. A flexible soil-steel structure assembled from galvanised corrugated plates, in which the surrounding backfill acts as part of the load carrying system.
This article explains the working principle, main types, typical applications, installation points, selection criteria, standards and frequently asked questions about galvanized corrugated steel culvert, and is intended for engineers, purchasers and project managers.
A flexible soil-steel structure assembled from galvanised corrugated plates, in which the surrounding backfill acts as part of the load carrying system.
Working principle: The product works through elastic deformation and mechanical interlock to provide reliable sealing or load transfer.
Galvanized Corrugated Steel Culvert is manufactured and inspected according to applicable national and industry standards. Hengshui Zhanhe Engineering Rubber Co., Ltd. carries out batch inspection before delivery, and inspection certificates together with third-party test reports (where required by the project) can be provided.
Typical standards applied to this product family include Chinese national and transportation industry standards; equivalent international standards can be referenced upon request.
A: Measure diameters as filling proceeds and keep the change within about two percent of diameter. Values approaching five percent call for stopping work and investigating, usually one sided placement or poor compaction.
A: No. The culvert is designed for open channel or very low head flow and its many bolted joints are not pressure tight. Pressurised supply requires dedicated pipe, and even inverted siphons need separate checks.
A: Ordinary soils are served by double sided hot dip galvanising of at least 600 grams per square metre. In acidic or poorly drained clays, or where groundwater fluctuates, increase the coating and add bituminous or epoxy protection based on measured resistivity and pH.
A: Before the soil arch forms a wheel load acts almost directly on the crown and can produce local overstress and ovaling. A minimum cover of about 0.5 m is typical, with axle limits set by the design documents.
Either a tonne rate or a metre rate applies. Steel grade and market movement come first, followed by corrosion protection where each step up in coating weight costs noticeably more and bituminous or epoxy layers add again. Fabrication matters too, since rolling, curving and accurate hole punching decide assembly speed. Freight is significant because large diameter components occupy volume, and the count of high strength bolts is a visible line item. Standard 1.5 m diameter round culvert is commonly quoted at 800 to 1800 CNY per metre.
Packing: standard export packing (woven bags, pallets or wooden cases). Delivery terms: EXW, FOB, CFR, CIF or DAP as agreed. Payment terms: T/T, L/C or other terms subject to negotiation.
