FAQ

Q: How do I determine the right wall panel specifications for my project?
A: Start with your structural engineer's requirements for fire rating, load-bearing needs, and thermal performance. Then match these against panel specifications. A good supplier will help you select the appropriate thickness and density based on your project requirements and local building codes.

Q: What is the typical lead time from order to delivery?
A: Standard production takes 15-30 days. Add 15-45 days for shipping depending on destination. For urgent orders, some suppliers can expedite production (at additional cost) or supply from existing stock.

Q: Can I mix different panel thicknesses in one order?
A: Yes, most suppliers can produce multiple thicknesses within the same order. This is common when projects have different wall types requiring different specifications (e.g., 75mm for interior partitions, 150mm for exterior walls).

Q: What should I do if panels arrive damaged?
A: Document the damage immediately with photos. Check the packaging for signs of mishandling. Contact the supplier within 48 hours. If you purchased insurance or agreed to CIF/DDP terms, file a claim per the contract terms. Reputable suppliers will replace damaged panels promptly.

Q: How do I handle specification changes after order placement?
A: Contact your supplier immediately. Changes are easiest before production begins. Once production starts, changes may incur additional costs and delays. Include a change order process in your contract from the beginning.

Q: Should I visit the factory before placing a large order?
A: Absolutely. A factory visit is strongly recommended for orders exceeding $50,000 or 2,000 m². It allows you to verify production capability, quality control processes, and build a personal relationship with the supplier team.

Q: What payment terms should I expect for a first-time order?
A: Standard terms for first orders are 30% deposit + 70% balance before shipment or by Letter of Credit. Repeat customers typically negotiate more favorable terms based on order history and trust.

Q: Can the supplier help with building code compliance in my country?
A: Many experienced export suppliers are familiar with various international building codes and can provide test reports and certifications relevant to your market. However, final compliance verification should be done by your local engineer or building authority.
