Generic, off-the-shelf gate packages rarely satisfy demanding site conditions. They struggle to accommodate sloped driveways, uneven ground lines, and high-duty automation cycles. Sourcing custom-engineered steel gates ensures every hinge post, structural roller box, and automated drive bracket is calculated to endure continuous mechanical stress and severe British weather.
At Has Metal Work (frequently designated as Has Metalwork across commercial building and facilities networks), we design, manufacture, and install turnkey perimeter entrance systems. Operating from our dedicated fabrication workshop on River Way in Harlow, Essex, and backed by our high-volume secondary production plant in Istanbul, Turkey, we supply main contractors, commercial property managers, and private clients across London and the Home Counties with precision-engineered custom metal gates.
Real Field Case Studies: Completed Gate Projects in Essex and London
Project 1: Automated Cantilever Sliding Security Gate – Harlow, Essex
- Project Scope: Design, workshop fabrication, and on-site commissioning of an 8-metre automated cantilever industrial sliding custom metal gate for a commercial logistics facility on River Way, Harlow.
- Materials & Finish: 120x120x6mm Square Hollow Section (SHS) perimeter frame, 30mm vertical solid square bars spaced at 100mm intervals, hot-dip galvanized to BS EN ISO 1461, and finished in a matte black powder coat (RAL 9005).
- Installation Details: Because heavy commercial delivery vehicles required unrestricted entry over an uneven approach, a tracked system was ruled out. Our team excavated and cast a reinforced structural concrete foundation for the counterbalance carriage. We integrated a 3-phase 400V industrial sliding motor, dual safety edges, photocell beams, and a GSM intercom unit.
- Turnaround: Detailed laser survey to final safety sign-off took 3 weeks, with the complete on-site install and motor programming finalized in 2 working days.
Project 2: Architectural Double-Leaf Swing Gates – Loughton, Essex
- Project Scope: Fabrication and installation of bespoke 4.5-metre wide, 2.2-metre high double-leaf driveway swing gates mounted to existing structural brick piers.
- Materials & Finish: Heavy-gauge 80x50x4mm rectangular steel framework with integrated composite timber privacy infill boards and heavy-duty adjustable spherical bearing hinges.
- Installation Details: To prevent structural loading on decorative masonry, our team installed internal structural steel box posts secured into the foundation using high-strength chemical anchors. Below-ground hydraulic gate operators were integrated with automated drainage loops to deliver an unobtrusive, modern finish.
- Turnaround: Manufactured, coated, and erected within 14 working days from technical drawing approval.
What Determines Custom Metal Gate Costs in the UK?
Accurately planning a perimeter entrance project requires understanding the primary technical factors driving custom metal gate fabrication and installation costs:
1. Gate Configuration and Opening Mechanism
- Double Swing Gates: Frequently provide the most cost-effective fabrication process because they rely on straightforward hinge geometry. However, they demand a level swing radius and adequate driveway depth clear of parked vehicles.
- Ground-Tracked Sliding Gates: Economical across wide openings but require continuous civil excavation to cast a level concrete strip footing across the entire roadway, adding ground preparation labor.
- Cantilever Sliding Gates: Require zero track excavation across the drive opening, making them ideal for gravel, sloping entrances, or high-tonnage vehicle yards. The extended counterbalanced tail frame increases raw steel tonnage, but eliminates road surface disturbance.
2. Steel Profile Weight and Infill Selection
- Light-gauge hollow box sections deteriorate rapidly under the rotational torque of commercial automation arms. We fabricate utilizing structural hollow sections with minimum 3mm to 6mm wall thicknesses.
- Infill choices—such as solid round bars, high-density privacy louvres, composite boards, or laser-cut decorative steel plates—directly impact workshop assembly hours and cutting time.
3. Surface Finishing and Corrosion Protection
- Untreated or Wet-Painted Steel: While cheaper initially, single-layer spray painting fails prematurely outdoors in the UK, leading to rust streaks and joint blistering.
- Duplex Coating System (Hot-Dip Galvanising + Architectural Powder Coating): The benchmark specification for exterior durability. Immersing the welded gate into molten zinc per BS EN ISO 1461 seals internal cavities, followed by electrostatic polyester powder coating to deliver a weather-resistant finish in any standard RAL color code.
4. Automation and Safety Hardware
- Integration of commercial automation systems—including underground hydraulic motors, mechanical drive racks, wireless safety ribs, infrared photocells, and keyless access control systems—influences total equipment and electrical commissioning costs.
Core Gate Configurations We Fabricate
Our Harlow workshop fabricates a wide variety of custom configurations engineered for commercial reliability and residential security:
- Industrial Cantilever Gates: High-security, trackless barrier systems engineered to span openings up to 12 metres without bottom ground interference.
- Automated Bi-Folding Speed Gates: Fast-acting trackless folding leaves designed for commercial sites and tight residential driveways where rapid cycling and space conservation are critical.
- Commercial Perimeter Swing Gates: Single and double-leaf structural steel gates engineered with heavy-duty adjustable hinges, tailored for business parks, utility compounds, and school perimeters.
- Pedestrian Security Gates: Dedicated side-access gates equipped with hydraulic self-closers, magnetic locks, panic crash bars, and anti-tamper latch plates.
Safety Standards and UK Building Regulations (BS EN 12453)
Power-operated automated custom metal gates are legally classified as machinery under UK law. Fabricators and installers must comply strictly with the Supply of Machinery (Safety) Regulations 2008 and BS EN 12453 (Safety in use of power-operated doors and gates).
To guarantee total compliance, our installation protocols integrate:
- Force Limitation and Pressure Testing: Calibrating operator torque profiles and force parameters with calibrated testing equipment to prevent crushing risks.
- Dual Anti-Entrapment Safeguards: Fitting optical infrared photocells and continuous tactile safety edges to reverse movement immediately upon detecting obstructions.
- Structural Anti-Drop Protection: Installing safety drop arrestor cables on vertical swing leaves to ensure that even in the unlikely event of hinge structural failure, the gate leaf cannot fall.
- Factory Production Control: Sourcing our structural steel plates and hollow sections exclusively from certified, audited mills with full Mill Test Certificates (MTCs).

Frequently Asked Questions
Do I need planning permission to install new driveway gates?
Under UK Permitted Development guidelines, gates adjacent to a highway used by vehicles generally do not require planning permission if they do not exceed 1 metre in height. If the gate is situated away from a highway, the height threshold is typically 2 metres. If your property is a listed building or located within a designated conservation area, planning approval may be required. We can provide technical elevation drawings to support your application.
What is the advantage of a cantilever sliding gate over a tracked sliding gate?
A cantilever gate requires no ground track across the entrance opening. It is suspended above the driveway, supported by heavy-duty internal roller carriages fixed to an engineered concrete foundation on one side. This eliminates issues associated with debris, leaves, snow, or gravel obstructing ground tracks.
Can your team automate existing manual steel gates?
Yes, provided your current gate leaves and posts are structurally sound and capable of handling continuous operational motor torque. We inspect hinge alignments, weld on reinforced motor mounting brackets, and install external linear rams, underground operators, and statutory safety systems.
How long does custom metal gate fabrication and installation typically take?
From completed on-site survey and CAD drawing approval, our standard lead time for bespoke fabrication, hot-dip galvanising, powder coating, and on-site fitting is generally 2 to 4 weeks.
