Fabricate a custom gate.

Beyond aesthetics, a professionally fabricated gate provides a robust physical barrier that can last for decades if treated correctly. In the UK's damp climate, the fabrication process must focus heavily on corrosion resistance and structural integrity to prevent sagging or rusting over time.

What Does the Work Involve?

• Site Survey: A specialist visits to take precision measurements, checking for ground levels, post requirements, and swing clearance.
• Design & Material Selection: Choosing between mild steel, wrought iron, or aluminium, and deciding on decorative elements like finials or scrolls.
• Workshop Fabrication: The metal is cut, shaped, and joined using professional MIG or TIG welding techniques based on a technical blueprint.
• Surface Treatment: The gate is typically sent for hot-dip galvanising (to prevent rust) and powder coating or specialist painting for the final finish.
• Hardware Integration: Fitting heavy-duty hinges, drop bolts, and high-security locks or electronic strike plates.
• On-Site Installation: Setting the posts in concrete (if required) and hanging the gates to ensure they are perfectly level and move freely.

Typical Costs

The cost of custom metalwork is primarily driven by the weight of the steel used and the complexity of the decorative scrolls or laser-cut patterns. Prices in 2025/26 reflect the continued high cost of raw materials and the specialist energy-intensive galvanising process.

Labour costs for a skilled blacksmith or fabricator typically range from £60 to £90 per hour. Complex decorative work or structural repairs to existing pillars will significantly increase the final quote.

How Long Does It Take?

• Initial Consultation: 1–2 hours for measuring and design discussion.
• Fabrication Lead Time: 3–6 weeks depending on the workshop's current backlog.
• Galvanising/Powder Coating: 5–10 working days (usually outsourced to specialist plants).
• Manual Installation: 4–8 hours on-site for a standard pair of gates.
• Automated Installation: 2–4 days to account for groundworks, cabling, and safety testing.

DIY or Professional?

Metal gate fabrication is strictly a professional task requiring industrial-grade welding equipment, metal benders, and cutting torches. While a DIYer might be able to hang a pre-made gate, bespoke fabrication involves structural calculations to ensure the gate's weight doesn't pull down the supporting pillars.

Safety is paramount: Automated gates must be installed by a professional to comply with UK safety regulations, preventing crush injuries or entrapment.

Choosing the Right Tradesperson

• Check the Workshop: A reputable fabricator should have a dedicated workshop where you can see work in progress.
• View a Portfolio: Look for photos of previous local installs to check the quality of the welds and the finish.
• Ask about Galvanising: Avoid any fabricator who suggests "primer and paint only" for outdoor steel; it will rust within two years.
• Questions to Ask:
  • Are the gates hot-dip galvanised to BS EN ISO 1461 standards?
  • What thickness of steel (gauge) are you using for the main frame?
  • Does the quote include all hardware, such as hinges and locks?
  • Can you provide a CAD drawing before fabrication begins?

UK Regulations

• Planning Permission: Generally required if the gate is over 1 metre high next to a highway, or over 2 metres elsewhere.
• Building Regulations: Not usually applicable for manual gates, but electrical work for automated gates must comply with Part P.
• Safety Standards: Automated gates must meet BS EN 12453 standards, including force-testing and the installation of safety photocells or pressure edges.
• Paperwork: You should receive a "Declaration of Conformity" and a maintenance logbook for any automated system.

Common Problems

• Inadequate Foundations: Heavy metal gates put immense strain on pillars; without deep concrete footings, the gates will eventually sag and fail to latch.
• Flash Rusting: This occurs when "cold galvanising" sprays are used instead of hot-dip baths, leading to rust bleeding through the paint within months.
• Poor Hinge Choice: Using undersized hinges for heavy bespoke gates leads to difficult operation and premature wear.
• Ground Clearance Issues: Failing to account for a rising driveway slope can result in a gate that hits the ground when opened.
