Henan Worthwill Industry Co., Ltd. is the international sales and export team working directly with affiliated aluminum manufacturing facilities in Gongyi, Henan, China.
This structure allows international buyers to communicate through an experienced export team while receiving factory-supported production, technical consultation, quality control, packaging and shipping services.
Our main product range includes:
Product availability depends on the required alloy, temper, thickness, width, surface treatment and order quantity.
Commonly supplied alloys include 1050, 1060, 1070, 1100, 3003, 3004, 3005, 3105, 5052 and 6061.
Common tempers include O, H12, H14, H16, H18, H22, H24, H26, H32 and T6.
Not every alloy or temper is suitable for every product form or application. Please tell us the intended use and forming process if you are unsure which material to select.
Our aluminum materials are commonly used in:
Material selection should be based on the actual operating environment, processing method and required performance.
Yes. Customers and authorized representatives can arrange a factory visit in advance.
Buyers who cannot travel to China may discuss a video call, remote factory presentation, production photos, inspection videos or third-party inspection.
Questions about dimensions, colors, coatings, processing and material selection.
Yes. Custom dimensions are available for many of our aluminum sheets, coils, strips, foils, circles and panels.
Please provide:
Minimum and maximum dimensions depend on the product, alloy, production route and surface treatment. Final feasibility must be confirmed before quotation.
Yes. Cutting and slitting services are available for suitable products.
Available processing may include:
Please provide the required finished dimensions and tolerances. For complex shapes, holes or machining requirements, send a technical drawing for review.
Yes. Custom colors are available for many color coated aluminum products.
You can provide:
Colors displayed on computer screens or mobile phones are not reliable enough for final approval. For projects with strict color requirements, a physical sample should be confirmed before mass production.
PE polyester coating is commonly used for general decorative, indoor and cost-sensitive applications.
PVDF coating is generally selected for architectural and outdoor projects requiring stronger weather resistance, UV resistance and longer-term color stability.
The correct coating depends on:
Please tell us where the material will be used instead of selecting a coating only by price.
Depending on the product, available options may include:
Gloss and appearance should be confirmed against an approved sample whenever visual consistency is important.
Yes. Protective film can be applied to suitable aluminum sheets, coated aluminum products and sublimation aluminum sheets.
Please confirm:
Protective film should be removed within the recommended storage and installation period to reduce the risk of adhesive residue.
Yes. We can review drawings, dimensional tables, CAD files, product photos or physical samples.
A useful drawing should show:
Complex processing or unusually tight tolerances may require a trial sample before mass production.
Yes. Please tell us how the material will be used and whether it will be bent, stamped, deep drawn, welded, machined, coated or exposed outdoors.
Useful selection information includes:
Our recommendation is based on the information provided. Final material selection should also be checked against your engineering and application requirements.
Mixed specifications may be possible, especially when they use compatible alloys, tempers, coatings and production routes.
However, each specification may have its own production minimum. Combining many small specifications may increase production loss, packaging complexity, cost and lead time.
Send us the complete specification list so that we can check whether the products can be combined into one production or shipment plan.
Information needed for accurate prices, trial orders and sample evaluation.
Please provide as much of the following information as possible:
A drawing, photo or previous product specification is also helpful. A request such as “Please quote aluminum sheet” is not enough because prices vary significantly by alloy, thickness, surface, processing and quantity.
A formal quotation can normally be prepared faster when all specifications are complete. Custom colors, complex processing, special tests or door-to-door logistics may require additional review.
MOQ is not the same for every aluminum product.
It depends on:
Stock or standard products may support a smaller trial quantity. Custom colors, unusual dimensions and special production runs normally require a higher quantity.
Small standard material samples can often be supplied free of charge for evaluation.
The buyer may need to pay for:
Sample availability depends on the requested alloy, thickness, color and surface finish.
Yes. A trial order may be possible for stock materials or products that can be combined with an existing production plan.
For custom-made materials, the feasibility of a small trial order depends on production minimums and setup costs.
Depending on the project, we may recommend:
Pricing is normally influenced by:
Very thin, unusually wide, unusually narrow or tight-tolerance products may have higher processing costs because they require more difficult production control or create more material loss.
Aluminum raw material prices, currency exchange rates and international freight costs can change.
For this reason, formal quotations normally include a validity period. If an order is confirmed after the quotation expires, the price may need to be recalculated.
A complete quotation should clearly state:
No. A lower price may result from differences in:
Before comparing offers, make sure each supplier is quoting the same specification. A cheaper material that is unsuitable for forming, printing, outdoor exposure or corrosion conditions may create much higher costs later.
Questions about inspection, certificates, standards, tolerances and quality claims.
Inspection items depend on the product and may include:
Special acceptance criteria should be stated before quotation and production.
Quality documents can be provided according to the product, order and agreed specification.
Available documents may include:
Not every document applies to every product. Required documentation must be confirmed before production.
Many aluminum products can be supplied with reference to recognized standards such as ASTM, EN, JIS or GB.
The applicable standard depends on the alloy, product form and intended use. Please provide the exact standard number and required revision. General descriptions such as “European standard” are not specific enough for production approval.
Yes. Third-party inspection can be arranged at the buyer's request.
The inspection agency, inspection scope, timing, acceptance criteria and cost should be agreed before production.
Inspection may cover:
Color consistency starts with an approved physical reference sample.
For projects with strict appearance requirements, we recommend:
Small differences may occur between separate coating batches. Buyers planning phased projects should discuss future color matching before the first order.
Tolerance depends on:
We do not use one tolerance value for every product. If your application requires a special tolerance, provide the exact requirement before quotation. Tighter tolerances may require additional processing, inspection and cost.
Contact us before processing or using the affected material.
Please provide:
Do not discard the packaging, labels or affected material until the issue has been reviewed. We will compare the evidence with the confirmed specification, production records and inspection data before discussing a solution.
Information about lead times, export packing, shipping and material storage.
Lead time varies according to:
Stock products can normally be prepared faster than custom production. The confirmed lead time should be stated in the quotation or sales contract rather than assumed from a general website estimate.
Packaging is selected according to the material form, dimensions, surface and shipping method.
Typical export protection may include:
Special packaging or container loading restrictions should be provided before quotation.
Yes. Packaging can be discussed according to the product and buyer requirements.
Possible options include:
Custom packaging may affect price, MOQ and preparation time.
Depending on the shipment and destination, methods may include:
Common trade terms may include:
The agreed Incoterm should include the named port or destination, such as FOB Qingdao, CIF Rotterdam or CFR Jebel Ali.
Standard shipping documents may include:
Production, packaging and loading photos or videos can also be discussed as part of the order process.
Please inform us before production if your customs authority, bank or end customer requires specific wording, certification or document formats.
Store aluminum products in a clean, dry and ventilated indoor area.
Recommended precautions include:
Incorrect storage may cause water staining, surface marks, oxidation or protective-film residue even when the material was delivered in acceptable condition.
Payment arrangements, support for first orders and handling after delivery.
Common payment methods include T/T and irrevocable L/C.
Other arrangements may be discussed depending on the order value, destination country, product, production requirements, customer credit and previous cooperation.
The final payment schedule must be clearly stated in the sales contract.
Yes. We understand that new buyers may want to verify product quality, communication and delivery performance before placing a larger order.
Depending on the product, we may support:
Custom production must still meet practical manufacturing minimums.
Our after-sales support may include:
The fastest way to investigate a problem is to provide complete evidence before the material is processed.
Send us the following details so that our team can review your application and prepare a more accurate quotation.
If you are unsure about the alloy or specification, explain how the material will be used. Our team will help review the available options.
