As a professional carbon steel heavy-duty hinge supplier, SKYSEN offers OEM/ODM services.
Base Material: High-quality Q235 carbon steel (ASTM A36 equivalent), high tensile strength (≥410MPa) and impact resistance, suitable for heavy-load scenarios.
Thickness: 5mm/6mm/8mm optional (customizable for special needs), thicker than standard hinges to enhance load-bearing capacity.
Surface Treatment: Electroplating (zinc/nickel) or hot-dip galvanizing, corrosion-resistant (salt spray test ≥48 hours), rust-proof and weatherproof for outdoor use (adapt to -40℃~60℃ temperature range).
Material & Craftsmanship
Base Material Options:Standard: A36 carbon steel (American standard equivalent to Q235), tensile strength ≥ 400MPa, suitable for general outdoor use.
Premium: 304/316 stainless steel (optional), for coastal, humid, or corrosion-prone environments.
Thickness & Structure:Hinge Leaf Thickness: 4mm/5mm/6mm (customizable), optimized for American fence gates (typical door weight 50-200kg).
One-piece forging or precision stamping (depending on size), no weld defects-ultrasonic tested for structural integrity.
Surface Treatment:
Carbon Steel: Hot-dip galvanizing (ASTM A123) + electrostatic powder coating (RAL colors available: black, brown, gray-classic American fence tones).
Stainless Steel: Passivation or brushed finish, rust-proof and low maintenance.
Corrosion Resistance:
Carbon Steel: 72-hour salt spray test (ASTM B117), suitable for most US climates (zones 3-9).
304 Stainless Steel: 500-hour salt spray test, ideal for coastal areas (Florida, California) or high-humidity regions.

FAQ
Q: Are these hinges compatible with standard American 4x4" fence posts?
A: Yes! The hinges are designed to fit US standard 4x4" (100x100mm) fence posts, with pre-drilled holes matching US 3/8" bolts. For 6x6" posts, we offer extended mounting plates (customizable upon request).
Q: What's the difference between carbon steel and stainless steel options for US climates?
A: Carbon steel (hot-dip galvanized + powder coated) works for most US regions (zones 3-9) and is cost-effective. 304/316 stainless steel is recommended for coastal areas or high-humidity regions, as it resists salt air corrosion better.
Q: Can these hinges be used for double swing ranch gates?
A: Absolutely. For double ranch gates (max width 3m, weight 300kg), we recommend using 3-4 pieces of 5"x4" (6mm thick) hinges (180kg load capacity each) - one top, one bottom, and one middle hinge per gate leaf for stability.
Q: Do you provide US standard mounting hardware (bolts, washers) with the hinges?
A: Yes, each hinge comes with US standard UNC-threaded bolts (3/8" x 2") and lock washers, made of the same material as the hinge (carbon steel or stainless steel) to ensure corrosion resistance and compatibility.
Q: How to reduce noise when opening/closing the fence gate?
A: All hinges include a nylon bushing between the pin and leaf, which eliminates metal-on-metal friction and reduces noise. For extra quiet operation, we offer optional rubber gaskets.
