Features

Precise Positioning: Engineered to hold rebar firmly in place, preventing displacement or sinking during the concrete pour, thereby ensuring accurate protective layer thickness.
Superior Strength & Durability: Manufactured from high-strength materials (e.g., Q235 steel or heavy-duty plastic), offering excellent compressive strength and bending resistance to withstand the weight of the rebar mesh and the impact pressure of wet concrete.
Easy & Efficient Installation: Features a user-friendly snap-in design; rebar rods click easily into the receptacles, eliminating the need for complex tying and significantly boosting construction efficiency.
Enhanced Stability: A wide base design provides excellent stability on various surfaces, preventing movement or tipping during the pour.
Anti-Corrosion Options: Available in galvanized steel or with plastic-tipped feet to prevent rust and protect waterproofing layers
