Explore our flagship precision-engineered door and gate solutions. Each system is designed to integrate seamlessly with smart access control, high wind load resistance, and premium thermal performance.
From architectural perimeter security to automated estate access, DERCHI integrates material science, structural engineering, and smart automation into custom driveway gates built for longevity.
Utilizing high-tensile 6063-T5 aluminum extrusions and solid A356 sand-cast aluminum panels, DERCHI driveway gates eliminate structural sagging across spans exceeding 8 meters while maintaining absolute dimensional stability.
Our 7-stage pretreatment and dual-layer AkzoNobel PVDF fluorocarbon spraying ensure anti-corrosion performance exceeding 3,000 hours in salt spray testing (ASTM B117), ideal for coastal and harsh climate installations.
Engineered for effortless automation, our gates support embedded underground swing actuators, heavy-duty rack-and-pinion sliding motors, and IoT smart home gateways with obstacle-sensing radar.
Unlike conventional wrought iron gates that suffer from rapid oxidization, excessive structural dead weight, and high maintenance costs, DERCHI’s engineered cast aluminum and thermally broken alloy driveway gates offer a 70% weight reduction with superior tensile strength (≥205 MPa). This dramatically extends motor duty cycles, protects hinge geometry, and guarantees rust-free operation for over 25 years.
Operating from our 180,000 m² state-of-the-art production facility in Foshan, DERCHI combines automated robotic welding, 5-axis CNC machining, and rigorous Quality Assurance to serve global B2B procurement demands.
By executing aluminum alloy extrusion, sand-casting, surface treatment, glass assembly, and motor bench-testing under a single roof, DERCHI eliminates sub-supplier delays. This centralized supply ecosystem ensures lead-time stability within 25 to 35 days for custom project orders.
Our production workflow utilizes automated 3D laser profiling and robotic MIG welding stations. Every gate leaves the production line with certified structural weld penetration, uniform powder thickness (60-80μm), and perfectly aligned pivot points.
A comprehensive engineering benchmark evaluating key structural material parameters to assist architectural specifiers and estate developers in selecting the optimal gate platform.

Detailed answers provided by DERCHI senior structural engineers addressing common procurement, technical, and installation queries.
For single-leaf swing gates, standard engineering allows up to 4.0 meters per leaf (8.0 meters total double swing opening). For cantilever sliding gate systems, DERCHI engineers single continuous leaves up to 12.0 meters clear span without ground track interference, utilizing internal counterbalance roller carriages.
Cast aluminum provides absolute immunity to red rust (iron oxide), eliminating the need for periodic re-sanding and repainting. Additionally, cast aluminum is approximately 65-70% lighter than solid iron of equivalent volume, which reduces motor torque stress by over 50% and dramatically extends the operating life of automation arms and floor hinges.
Yes. DERCHI gates feature internal structural reinforcement channels (minimum 5mm aluminum wall thickness) dedicated to mounting points for linear rams, articulated arms, or underground hydraulic motors. We supply standardized mounting bracket prep matching all major global motor brands upon request.
