Frequently Asked Questions
Q1: What is the load capacity of your 25×3mm bar grating with 100×100mm spacing?
This configuration is suitable for light to medium pedestrian traffic and light industrial loads. For specific load requirements, please provide the span and we can calculate the maximum uniform load. Custom bar sizes are available for heavier applications.
Q2: Can I order a different size or mesh spacing?
Yes, we offer customizable options. You can change the flat bar size, cross bar spacing, panel dimensions, and surface type (serrated or plain). Please contact us with your requirements.
Q3: What does the Mill Test Report include?
Our Mill Test Report documents the chemical composition (e.g., carbon, manganese, silicon content) and mechanical properties (yield strength, tensile strength, elongation) of the steel used in the grating. It ensures the material meets industry standards and provides traceability for your quality control.
Q4: How is the grating packaged for export?
We pack the gratings in bundles with steel straps, and each bundle is wrapped with waterproof paper or plastic sheeting to prevent damage during transit. For small orders, wooden crates can be used upon request.
Q5: What is the typical lead time for a standard order?
For standard sizes (25×3mm, 100×100mm), the lead time is around 15–20 working days after receiving the deposit. Custom orders may take 20–30 working days depending on complexity.
Q6: Does the 1-year warranty cover all defects?
The warranty covers manufacturing defects such as weld breakage, galvanizing peeling, or material failure under normal use. It does not cover damage caused by misuse, improper installation, or extreme chemical exposure. Please refer to our warranty policy for full details.
Q7: Do you offer samples before bulk order?
Yes, we provide free samples of standard sizes (approximately 300×300mm piece) with the buyer bearing the shipping cost. For custom samples, a small fee may apply. Contact us for sample requests.
Q8: Can I get a serrated surface for anti-slip requirements?
Yes, we can produce serrated (toothed) bar grating for enhanced slip resistance. The serrations are pressed into the bearing bars during manufacturing. Please specify this requirement when placing your order.
With decades of experience and a dedicated production team, Anping County Boli Hardware Wiremesh Products Factory is your reliable partner for galvanized bar grating. We look forward to serving you with quality products and professional service.
