Metal concrete funnels (also called concrete placement funnels or tremie funnels) are used in construction to direct concrete flow into formwork, pile foundations, columns, and confined spaces. They are an essential site tool for any contractor placing ready-mixed or site-mixed concrete in locations where direct chute access is impractical. Common specifications: mild steel (Q235 or S235JR grade), 3–6mm wall thickness, cone angles of 60–120°, outlet diameters from 150mm to 350mm, and inlet diameters from 400mm to 800mm. Galvanised steel versions are preferred for repeated use in wet environments. Heavy-duty cast iron funnels are used for permanent or semi-permanent installation. Surface finishes include hot-dip galvanising, epoxy coating, and plain mill finish. For wholesale procurement, funnels are typically sold per piece or in pallet lots of 10–50 pieces. Custom dimensions — outlet diameter, cone angle, handle attachment type, and flange pattern — are available from most steel fabricators at MOQs of 20–50 pieces. Buyers should specify wall thickness, material grade, surface treatment, and any connection standard (e.g. BS, DIN, ASTM flange dimensions) when requesting quotes.
