BEFORE YOU ASK

The short answer: bring us the opening.

Most questions resolve to the same input: the opening schedule. Sizes, quantities, destination and a target date give you a real answer in one reply instead of five.

What information is needed for a custom window and door quote?

Send an opening schedule with dimensions, quantities, opening types, glazing and finish preferences. Include the destination, building use, required performance and delivery expectations.

Can I enquire about several product categories together?

Yes. List each category and quantity in one project brief, then confirm compatibility, scope and commercial terms for the selected systems.

What is the minimum order quantity?

Minimum quantities depend on the product and configuration. Share your required mix and quantities to request the applicable order conditions.

What are the production and shipping lead times?

Timing depends on specification approval, order quantity, production scheduling and transport route. Request a written schedule for your order.

Are thermal and acoustic performance figures available?

Ask for system-specific documentation. Performance depends on the frame, glass, seals, dimensions and tested configuration; confirm suitability against local project requirements.

Are you a factory or a trading company?

We are a factory-side supplier. Production runs in Foshan, Guangdong, with our own QC and export packing handled in-house, so the team that quotes your project is the team that follows it through drawing, production and loading. There is no intermediary layer between your specification and the workshop.

How long does delivery take to my destination?

Delivery time depends on the destination, not on a single published number. Production is typically 25–35 days after drawing approval, then sea freight adds roughly 25–35 days to US west coast ports, 30–40 days to Europe and the UK, and 18–28 days to the Middle East and South East Asia. Door-to-door and air options are available for samples or urgent phases. Send the destination port or postcode and we will confirm the actual schedule for your quantities.

Why is your pricing competitive?

We buy profiles, glass and hardware in the same Foshan industrial belt where we manufacture, in project volumes, and we quote item by item so you can compare like for like. Factory-direct supply removes distributor margin, and our packing method keeps damage claims low, which protects the landed cost rather than just the unit price.

Can I request samples?

Discuss the sample type, intended review, availability, cost and shipping destination with the team before arranging a sample order.

Do you provide installation?

Confirm the installation scope, drawings and site responsibilities in your enquiry. Do not assume on-site installation is included in a product quotation.

How do I discuss after-sales or technical support?

Use the contact form and select the relevant support enquiry type. Include your order reference and a description of the issue; photographs can be shared through the agreed follow-up channel.
