Standard Galvanised Steel Guardrail
The standard galvanised steel guardrail is made mainly from galvanized steel tubes. Posts, horizontal rails, vertical bars and connecting parts form a complete outdoor boundary system. The product normally uses an assembled structure, which reduces the need for welding at the installation site.
Pre-Assembled Structure for Outdoor Boundary Projects
The standard galvanised steel guardrail is made mainly from galvanized steel tubes. Posts, horizontal rails, vertical bars and connecting parts form a complete outdoor boundary system. The product normally uses an assembled structure, which reduces the need for welding at the installation site.
This modular design makes the guardrail easier to pack, transport and install. Individual components can also be removed and replaced when maintenance is required. It is suitable for residential communities, schools, parks, factory boundaries, community roads, commercial buildings, courtyards and public green spaces. The guardrail can be used for boundary definition, pedestrian guidance and area separation.
Common guardrail heights range from 800 to 2,400 mm. Several post, horizontal rail and vertical bar sizes are available to match different installation locations and enclosure requirements.
Galvanized Base and Powder-Coated Finish
The galvanized steel base can be combined with an electrostatic powder coating to form a multi-layer surface protection system. Powder coating also provides a choice of colors, surface textures and gloss levels, allowing the product to match different buildings and landscape designs.
For coastal, humid or industrial environments, buyers should consider the actual corrosion conditions before confirming the surface treatment. Cut edges, connection holes, welded areas and fasteners require particular attention. Outdoor durability should not be judged only by the visible color of the finished guardrail.
The standard galvanised steel guardrail can be manufactured with vertical bar spacing from 80 to 120 mm. This spacing may also be adjusted according to the intended users, project safety requirements and applicable local regulations.
Custom Dimensions and Factory Processing
Nantong Yinuo Metal Technology Co., Ltd. can support structural confirmation, metal processing, powder coating, packaging, delivery and installation coordination.
The factory is equipped with laser cutting machines, laser tube cutting machines, robotic welding machines, bending machines, punching machines and milling machines. These facilities are used for tube cutting, hole processing, bending, welding, grinding and surface finishing.
Before production, the project team can review the installation position, required fence height, foundation type and site dimensions. The post section, horizontal and vertical rail sizes, bar spacing, surface color and installation method can then be confirmed according to the project conditions.
Customization is available according to CAD drawings, 3D models or physical samples. Dimensions, colors, patterns, styles and brand markings can be discussed and confirmed for each order.
Order Management, Inspection and Packaging
The minimum order quantity for regular small guardrails is 10 pieces. Different colors or styles can be combined within the same order. A pre-production sample can also be arranged to confirm the dimensions, color and surface finish before batch manufacturing.
For a simple standard product, the normal production and shipment period is approximately 7–10 working days after the deposit is received. During production, photos or videos of material processing, welding, powder coating and finished products can be provided every 3–5 days.
Before packing, each standard galvanised steel guardrail is checked for dimensions, welding quality, paint condition and visible defects. Foam corner protection is added to exposed edges. The products are then secured with an external frame and stretch film to reduce the risk of damage during long-distance transportation.
