wrought iron fence specification for Canada
wrought iron fence for Canadian conditions, consider both durability and compliance with local standards. Here’s a breakdown of key specifications:
1. Material and Coating
Steel Grade: Opt for high-quality wrought iron or mild steel, which is strong and durable.
Corrosion Protection: Galvanized steel with a powder-coated finish is ideal for Canada’s climate. Powder coating adds a layer of protection against rust and wear from moisture and temperature fluctuations.
UV Protection: A UV-resistant coating is recommended to prevent fading and maintain appearance in sunny regions.
2. Dimensions and Structure
Post Thickness: Posts should typically be 2–4 inches in diameter for stability and strength.
Pickets: 1/2 to 3/4-inch diameter pickets are standard; spacing is often around 4 inches to comply with safety codes.
Fence Height: Standard heights range from 4 to 8 feet, with residential areas typically limited to 4–6 feet. For security purposes, fences of 6 feet or higher may be ideal.
Panel Width: Panels are often 6–8 feet wide, which makes them sturdy and cost-effective for installation.
3. Foundation
Depth of Footings: To handle Canada’s frost depth, footings should typically be buried 4 feet deep (depending on the frost line in your area) to prevent shifting and heaving.
Concrete Footings: Set posts in concrete to secure the fence in place; this is especially critical for regions with freeze-thaw cycles.
4. Safety Standards
Spacing Compliance: Check with local building codes, as they often regulate the maximum gap between pickets (typically no more than 4 inches) to prevent children or animals from getting stuck.
Top Design: For added security, consider pointed finials or curved tops to deter climbing.
5. Installation Guidelines
Welding Standards: Ensure welded joints are high quality to prevent rusting and breakage.
