Close-mesh iron grilles have tighter, stronger wires for better security. Curtain grilles use wider spacing for a lighter look. For exterior windows and doors in Riyadh or Jeddah, choose a close-mesh grille with rust-resistant coating to improve security, heat resistance, and long-term stability.
For interior windows, 2 to 2.5 mm is usually enough. For exterior doors and damp or coastal openings in Dammam or Jeddah, use 3 mm or more. Thicker iron improves strength against bending, pulling, and forced entry while keeping the frame secure.
Rust resistance depends on coating and maintenance. Powder-coated or rust-treated grilles perform better in hot, humid coastal areas. Matkel offers exterior-grade options with protective finishes. Regular dusting and periodic inspection help maintain appearance and prevent corrosion near the sea.
Popular square mesh sizes are 5x5 cm, 7x7 cm, and 10x10 cm. Smaller openings provide stronger protection and reduce insect entry. Larger openings suit ventilation-focused areas. Select based on window size, location, and whether the space needs security, airflow, or both.
Price depends on iron thickness, mesh size, coating, and total area. Installation cost can vary by window height, access, and reinforcement needs. Matkel can provide a quote after measuring the opening in Riyadh, Jeddah, or Dammam to match the correct security and finish level.
