Product & supply guidance
Box Culvert: questions before ordering
What is Box Culvert used for?
Precast reinforced concrete box culverts for higher-capacity drainage and small culvert crossings. Typical applications include high-capacity stormwater drainage, road and access crossings, infrastructure culvert works. Confirm the required specification against your project drawings.
Which box culvert dimensions should I use?
Use the drawing and table for the required small-size or standard-size box culvert. Read each dimension against its matching drawing symbol: internal opening dimensions are not interchangeable with overall dimensions. Confirm the project specification and loading requirements before ordering.
Where can I find Box Culvert sizes and drawings?
The specification section above contains the available Malaysia catalogue product data. Read dimensions together with the relevant image or drawing and the table notes. Where a value is not listed, request confirmation from Kenglobal rather than assuming it from another product.
What information should I send for a quotation?
Send the product type, dimensions or drawing reference, quantity, project location and required delivery date. Include reinforcement and loading requirements where specified. Kenglobal can then review the requirements and confirm the quotation, availability and delivery arrangements.
