▎Frequently Asked Questions (FAQ)
Q1: What is a Mill Test Report (MTR) and why is it important?
A: A Mill Test Report is a quality assurance document provided by the steel mill that certifies the chemical composition and mechanical properties of the 304 stainless steel used in your grating. It confirms the material meets specifications such as ASTM A240, giving you traceability and confidence in the product’s performance, especially for critical applications.
Q2: Can I order non-standard sizes? What is the lead time?
A: Yes, we specialize in custom sizes. You can specify any width, length, bar spacing, and thickness. Typical lead time for custom orders is 7–15 days after confirmation, depending on complexity and quantity. We offer flexible production to fit your schedule.
Q3: What is the warranty coverage?
A: We provide a 1-year warranty against manufacturing defects, including issues like weld failure, incorrect dimensions, or material flaws. The warranty does not cover damage caused by misuse, improper installation, or environmental factors beyond standard design limits. Contact us for full warranty terms.
Q4: How do I determine the load capacity needed for my project?
A: Load capacity depends on bearing bar height, thickness, spacing, and support span. Our engineering team can calculate the appropriate grating specifications based on your required load (e.g., pedestrian, light vehicle, or heavy machinery). Please provide the span and load data, and we will recommend the optimal design.
Q5: What surface finishes are available?
A: The standard finish is mill finish (no additional treatment). We also offer pickling and passivation to remove heat tint and improve corrosion resistance, as well as mechanical polishing for aesthetic applications. These options are available at an additional cost.
Q6: Can these gratings be used in food processing or marine environments?
A: Yes, 304 stainless steel is widely used in food processing (non-reactive, easy to clean) and marine environments (good saltwater resistance). For highly aggressive environments (e.g., chlorides or acids), we recommend 316L stainless steel – please consult our sales team for advice.
Q7: What are the typical packaging and shipping methods?
A: Gratings are securely bundled with steel straps, wrapped in protective material, and loaded into containers or on flat racks. We ship from Port of Tianjin or Port of Qingdao via sea freight. For small orders, we also offer air freight or express courier options upon request.
Q8: Do you provide samples before bulk order?
A: Yes, we can provide small samples (e.g., 200x200 mm) for quality evaluation. Sample cost is payable by the buyer, but we will refund the amount for confirmed bulk orders. Please contact us to arrange sample delivery.
