Introduction
When you finish picking your perimeter fence panels, the next big decision is selecting suitable entry gates, and double gates are one of the most popular picks for large openings. Whether you need vehicle access for warehouses, construction yards, commercial parks or residential compounds, double gates create a wide, unobstructed passage that single gates simply cannot match.
Many buyers only focus on gate appearance at first, ignoring load capacity, corrosion resistance and matching fence specifications. This often leads to sagging hinges, rust spots or mismatched styles soon after installation.
As a professional fencing manufacturer, Giant Fence supplies complete fencing systems including double gates. Our welded mesh fencing products are manufactured following UNE‑EN‑10223‑7:2013. We strictly control steel wire material, coating weight and welding quality during production. We also adopt the ISO 9223:2012 atmospheric corrosion classification system to develop targeted anti‑corrosion coating options. Under ideal operating conditions, with no surface damage and proper installation, each coating option can reach its theoretical service life.
This easy‑to‑read guide walks you through all key points you need to check before ordering your double gates, helping you make a smart choice for your fencing project.
Basic Understanding of Double Gates
Unlike single swing gates with one leaf, double gates consist of two gate leaves that swing open from the middle. This design shines when you need a wide opening for trucks, heavy machinery or large equipment. You can open both leaves fully for big vehicles, or just one leaf for pedestrian access on a daily basis.
A common mistake is buying double gates that do not match your fence panels in material or style. If gate frames and fence mesh use different raw materials or coating processes, they will age unevenly. Giant Fence designs its double gates to perfectly pair with our fence panels, maintaining a consistent look and uniform quality standard for the whole perimeter system.
Core Factors to Select Your Double Gates
Gate Opening Width
Start by confirming the maximum width you require. Measure the entryway carefully and think about what will pass through. For regular cars, a narrower double gate works fine; container trucks or construction machinery demand a much wider opening. Keep extra clearance in mind to avoid scraping vehicles when opening and closing the gates.
Frame Strength & Wire Specs
The frame is the backbone of double gates. Larger and heavier gate openings need thicker, more robust frames to prevent sagging over time. The mesh fitted on the gate follows the same production rules as our fence panels under UNE‑EN‑10223‑7:2013, so welding strength and steel quality stay reliable. Always share your expected load and usage frequency with Giant Fence, so we can recommend a suitable frame thickness.
Swing Direction & Space
Check available space on both sides before deciding swing direction. Swing inward requires free space inside your site; swing outward needs clear space outside. Never install double gates where the swing path hits walls, slopes or obstacles, otherwise the gates cannot fully open and will wear hinges quickly.
Lock & Hinge Hardware
Hardware is easy to overlook but critical for long‑term use. Hinges carry the full weight of double gates, while locks control site security. Giant Fence provides matched heavy‑duty hardware together with gates. For high‑security industrial sites, we can upgrade to anti‑tamper locking systems.
Anti‑Corrosion Coating Options Based on ISO 9223:2012
Just like fence panels, double gates face different corrosion risks depending on location. Giant Fence matches coatings according to ISO 9223:2012 corrosion grades:
C1‑C3 Low to moderate corrosion, inland areas
Most inland residential zones, schools and regular industrial parks fall into this category. Our standard hot‑dip galvanized plus powder coated double gates are a cost‑effective solution here. With proper installation and no scratches, they can reach the expected service life.
C4‑CX High to extreme corrosion, coastal & heavy industrial zones
Salt spray along coastlines and chemical pollutants in heavy industrial areas speed up rusting. Standard coatings will fail rapidly. Giant Fence supplies upgraded heavy anti‑corrosion double gates for these tough environments, using enhanced galvanization plus premium outdoor powder coating to slow corrosion.
Note: The theoretical service life of coatings only applies under ideal conditions. If the coating gets scratched or struck, bare steel will be exposed and local rust may appear. Regular visual inspection is recommended after installation.
Typical Application Scenarios for Double Gates
double gates are widely used for sites that need wide entryways:
✅ Factory and warehouse vehicle entrances
✅ Construction site perimeter access
✅ Commercial parks and logistics yards
✅ Large residential communities
✅ Farmland and livestock enclosures
✅ School and municipal large entry points
Practical Buying Tips
Keep double gates consistent with your fence panels. Ask Giant Fence to match mesh style, color and coating, so the whole fence looks integrated.
Calculate usage frequency. High‑traffic sites need reinforced frames and heavy‑duty hinges to stop sagging.
Confirm ground conditions. Sloped ground may need custom‑adjusted gate frames to avoid jamming.
Think about extra accessories. Gate stoppers, drop bolts and warning signs can improve safety and daily operation.
Request samples or technical drawings before mass production for custom sized double gates.
Frequently Asked Questions
Q1: Does UNE‑EN‑10223‑7:2013 apply to double gates?
A1: The mesh section of our double gates is manufactured following UNE‑EN‑10223‑7:2013. The standard regulates steel wire material, coating weight and welding workmanship to guarantee stable quality. Giant Fence applies these quality controls for our gate mesh.
Q2: Can double gates be used in coastal projects?
A2: Yes, but you need to select the upgraded anti‑corrosion version. Coastal sites usually belong to ISO 9223:2012 C4‑CX grade. Standard coated double gates cannot resist salt spray well. Contact Giant Fence for coastal grade solutions.
Q3: Will heavy double gates sag after years of use?
A3: It depends on frame design and hinge quality. If you choose properly reinforced frames and heavy‑duty hardware from Giant Fence and install correctly, sagging can be greatly reduced. Regular maintenance of hinges also helps extend service life.
Conclusion
Choosing the right double gates is not only about picking a style you like. Gate width, frame strength, swing space, hardware and anti‑corrosion coating all matter.
Giant Fence manufactures gate mesh following UNE‑EN‑10223‑7:2013, and provides coating plans aligned with ISO 9223:2012 for C1‑C3 inland and C4‑CX coastal or heavy industrial environments.
