Standard samples are free. For each SKU, you may request 2 coated panels, a 800g powder sample, or both. International courier charges are paid by the customer. Additional quantities, custom colors or special formulation samples may be chargeable, and any fee will be confirmed before preparation.

Yes. Multiple products can be included in one request. For each product, you may request 2 coated panels, a 800g powder sample, Additional quantities or special samples may require separate confirmation and charges.

Yes, in two ways:

Standard RAL colors listed on our website: you can place an order directly at the listed price;

Colors not listed: we support custom color matching based on RAL or Pantone codes, or physical samples provided by the customer. Upon receiving the color code or sample, we will prepare a color panel for your confirmation before production.

In either case, the final color is subject to the mutually approved panel, with color difference (ΔE) controlled within the agreed tolerance.

Please provide the following details to help us match the right product and prepare samples quickly:

Workpiece & application: what the product is and how it will be used;

Service environment: indoor or outdoor use;

Substrate & pretreatment: e.g., aluminum, galvanized parts, with pre-anodizing, sandblasting or other treatments;

Color: RAL/Pantone code or a physical color sample;

Gloss & surface effect: e.g., high gloss, matte, sand texture, hammer finish;

Curing conditions: oven temperature and curing time;

Target film thickness;

Performance requirements: e.g., weather resistance, corrosion protection, electrical insulation;

Estimated purchase volume.

The more complete the information, the more accurate the product match — and the faster the sampling and quotation.

Custom colors, special performance or repeated development is chargeable. Any fee is confirmed before sample preparation.

• Existing standard samples are normally shipped within 3 business days after confirmation.

• Lead time for custom colors or formulations depends on development complexity.

Yes, in two steps:

Trial spray first: request standard sample powder to verify color, powder pickup and curing;

Small-batch line trial: for quantities beyond the standard sample size, we will confirm availability and pricing based on current stock, color and production schedule.

Please contact our sales team with your testing needs (quantity, color and timeline), and we will get back to you with a solution promptly. [email protected]

Yes. A pending sample request can be cancelled by contacting our service team.

Standard samples: cancellable before packing or shipment; shipping costs already incurred are non-refundable.

Custom samples: Generally non-cancellable once color matching, sample preparation or production has started; development, sample and shipping costs already incurred are non-refundable.

Production strictly follows the specifications confirmed by both parties, with full-process quality control covering:

· Incoming inspection of raw materials;

· In-process parameter control (e.g., extruder speed, sieve mesh size);

· In-process panel preparation;

· Color, gloss and surface appearance checks, plus necessary physical and performance tests;

· Pre-shipment batch review.

For key projects, sampling or trial production can be arranged before mass production. All production and inspection data are recorded in our system and can be shared with the buyer upon request.

We recommend a trial spray with samples first, recording the following parameters:

· Substrate and pretreatment;

· Spray gun type and voltage;

· Film thickness;

· Oven set temperature and actual workpiece temperature;

· Curing time;

· Appearance and performance results.

If issues such as poor powder pickup, leveling problems, pinholes, color difference or curing defects occur, please send the parameter records and photos to our technical team [email protected], and we will help analyze the cause and suggest adjustments.

Locked formulation and colorants: The formulation and raw material suppliers remain consistent.

Approved standard retained: We retain the approved color panel and formulation record.

Batch release comparison: Each batch is sprayed under specified film thickness and curing conditions, then checked for color, gloss and surface appearance before release.

Please retain the original packaging, batch number, coated panels and production records, and contact us promptly. We will review the agreed TDS specifications, batch records, retained samples and application conditions. If a product quality issue is confirmed, we will provide a replacement, resupply or refund.

Standard products normally require 3–7 business days. Lead time for custom colors, special formulations and large orders is confirmed with the formal order.

• International courier for samples

• Air freight for small or urgent orders

• Rail freight for selected European and route-accessible destinations

• Ocean freight for regular bulk orders

Yes. If your appointed forwarder handles pickup and all export operations, the related logistics charges are settled directly with the forwarder.

Once the goods are dispatched, we will provide you with the bill of lading number (B/L No.) and vessel/voyage details, so you can track the shipment in real time on the carrier's website or the forwarder's tracking platform.

We will also follow up on key milestones such as departure and arrival, and keep you updated.

Alternatively, you may contact us directly for shipment status — please provide your Order ID so we can locate your order quickly.
