Heavy-Duty Weld-On Steel Butt Hinges (Un-Drilled / Plain Square Hinges)

Engineered for direct welding onto steel structures, these un-drilled heavy-duty iron butt hinges deliver permanent pivot support for industrial cabinets, security gates, furnaces, and metal enclosures. Manufactured from high-strength mild steel with a polished plain surface, they allow for seamless arc or MIG welding without pre-drilled screw holes.

Key Features

• Weld-On Un-Drilled Design: Flat, hole-free leaves facilitate fast, robust welding directly onto steel frames and metal plates.
• Thickened Heavy-Duty Profile: Available in heavy-gauge steel up to 3.0 mm thick to handle high loads without bending or warping.
• Polished Raw Steel Finish: Clean surface finish ensures optimal weld penetration and immediate paint or powder-coating adhesion post-welding.
• Compact Pivot Strength: Compact square geometry delivers reliable alignment and smooth movement for heavy industrial doors and lids.
