Q1: What are the core differences between single-layer and double-layer guardrails, and how to choose?

A1: The core differences lie in protection level and structure: the single-layer version has a single crossbar and 3mm wall thickness, suitable for ordinary protection (pedestrian and small tool impact) with high cost-effectiveness; the double-layer version has two crossbars and 3-5mm wall thickness, doubling the anti-collision performance, suitable for high-strength protection (vehicle and heavy equipment impact). You can choose according to protection needs and scenario intensity, and we can provide exclusive selection suggestions for bulk purchases.

Q2: What is the adaptable protection size range, and is customization supported?

A2: Both single-layer and double-layer versions support customization, with regular length 500-2000mm and height 800-1200mm. The length, height and crossbar spacing can be adjusted according to site corners and equipment dimensions; the L-type angle can be fine-tuned (85°-95°), accurately fitting corner scenarios and adapting to various irregular protection needs.

Q3: Is there any difference in MOQ and lead time between single-layer and double-layer versions?

A3: No difference. Both standard versions (single-layerdouble-layer) have an MOQ of 1 set, with sufficient stock for same-day shipment; customized versions (single-layer/double-layer) have an MOQ of 30 sets, with a regular lead time of 7-10 days. Bulk customization (over 100 sets) can be shortened to 5-7 days, supporting rush production.

Q4: What installation accessories are included, and is installation guidance provided?

A4: Each set is equipped with a full set of accessories including thickened flange, high-strength expansion bolts and waterproof gaskets (the double-layer version is additionally equipped with reinforced connectors); detailed Chinese and English installation manuals and video tutorials are provided, with remote installation guidance available. For complex corner scenarios, we can assist in formulating exclusive installation plans.

Q5: Can product certifications and test reports be provided to meet overseas market needs?

A5: Material test reports and anti-corrosion performance test reports can be provided, and CE certification application is supported, fully meeting the access requirements of overseas markets such as Europe, America, Southeast Asia and the Middle East. Corresponding test items (such as anti-collision performance test) can be supplemented according to customer-specified standards.

Q6: How is overseas transportation packaged, and is FCL/LCL shipping supported?

A6: Three-layer packaging is adopted: EPE foam wrapping + woven bag sealing + wooden frame reinforcement to prevent collision and deformation during transportation. We support full container load (FCL) and less than container load (LCL) shipping, provide fumigation certificates and customs declaration documents, and assist in connecting with overseas logistics and customs clearance matters to reduce transportation loss.

Q7: What is the product warranty period, and is there any difference between single-layer and double-layer warranties?

A7: There is no difference in warranty. The powder coating has a 3-year warranty, and the main steel structure has a 5-year warranty. Free replacement parts are provided for non-man-made damage during the warranty period (the double-layer version includes reinforced crossbar accessories); we offer lifelong technical support and can assist overseas customers in connecting with local maintenance resources.

Q8: Is it possible to upgrade single-layer to double-layer, and customize logo and warning text?

A8: Customization adjustment is supported. The single-layer version can be upgraded to double-layer according to needs (corresponding costs need to be supplemented); brand logos and warning texts (such as "No Collision") can be customized via laser engraving and screen printing processes, supporting customization of warning colors and reflective strip installation to enhance brand image and warning effect.
