FAQ

Our hardware products are widely used across multiple sectors, including residential interior fit-outs, commercial building projects, hotel and hospitality renovations, office furniture manufacturing, and bulk distribution for hardware wholesalers. We also supply project contractors handling large-scale construction and renovation work.

Yes, we welcome factory visits from prospective and existing customers. You can tour our material warehouse, stamping workshop, precision press workshop, automated assembly line, and quality inspection area. Please contact us in advance to schedule your visit so we can arrange a proper reception and factory tour.

HongHe operates in compliance with recognized quality standards. Our products are SGS tested and undergo salt spray and durability testing. We follow ISO-compliant manufacturing processes and hold utility model and structural patents. Export qualification and compliance records are available upon request.

Our factory is located at No. 007, Row 1, Middle Section of Songwang Avenue, Songshan Industrial Zone, Yuecheng Town, Jieyang, Guangdong, China. Jieyang is one of China's leading hardware manufacturing clusters, known for its mature supply chain and skilled labor force.

We accept most standard engineering file formats, including CAD files (DWG, DXF), 3D models (STEP, IGES, X_T, STL), PDF technical drawings, and physical samples for reverse engineering. If you only have a concept or rough sketch, our engineering team can help refine it into a production-ready drawing.

Yes, we are fully willing to sign Non-Disclosure Agreements (NDAs) before receiving any proprietary drawings or design files. We treat all customer designs and technical data as strictly confidential and never share them with third parties.

Yes, we provide full ODM services. Our in-house engineering team can work from your concept sketches, rough drawings, or reference samples to develop new hardware products. The process includes drawing review, prototype development, sample testing, and production optimization before mass manufacturing begins.

We support full OEM customization including custom materials (stainless steel, iron, zinc alloy, aluminum), custom dimensions and tolerances, surface finishes (brushed, polished, satin, chrome, black, gold, antique), custom packaging with your branding, and logo engraving or printing. We work from your drawings, samples, or detailed specifications.

Yes, we can produce custom samples based on your drawings, specifications, or reference samples. Custom samples may involve a sample fee depending on the level of tooling or engineering work required. The sample fee is usually refundable once you place a bulk production order.

While the samples themselves are free, the shipping cost is typically covered by the customer. We can ship via DHL, FedEx, UPS, or other express services based on your preference. We will provide the exact shipping cost before sending so you can confirm.

For standard products in stock, samples can be shipped within 1–3 business days. For custom or OEM samples that require new production, the typical sample lead time is 7–15 days depending on complexity. Shipping time depends on your location and chosen logistics method.

Yes, we offer free samples for standard hardware products to help you evaluate material quality, surface finish, dimensional accuracy, and overall functionality before committing to a bulk order. Samples are available for brand owners, wholesalers, and project buyers who are planning OEM or bulk purchases.

Yes, we support mixed-product orders. You can combine different hardware categories — such as hinges, drawer slides, door locks, and handles — in a single shipment. This is especially useful for wholesalers and project buyers who need a complete hardware solution from one supplier.

Yes, we support trial orders to help new customers evaluate our product quality, packaging, and delivery performance before scaling up. Trial order quantities and pricing can be discussed based on your specific product and market needs.

We accept T/T (bank transfer), which is the most common method for international orders. For new customers, we typically require a 30% deposit before production and the remaining 70% balance before shipment. Other payment arrangements can be discussed for long-term partners.

Our MOQ is flexible and varies depending on the product type and customization level. For standard products, the MOQ is generally negotiable and can be adjusted for trial orders. For fully customized OEM products, the MOQ depends on tooling and production setup requirements. Contact us with your specific needs for a clear answer.

We support multiple shipping options including sea freight (FCL and LCL), air freight, and international express (DHL, FedEx, UPS). The best shipping method depends on order volume, destination, and urgency. We can also deliver to your designated freight forwarder or port if preferred.

Yes, we maintain inventory for hot-selling standard models that can be shipped quickly — often within 1–3 business days. For high-volume or repeat-order customers, we can also arrange safety stock arrangements to shorten lead times on recurring orders.

We maintain a practical production planning system and in-house manufacturing control to ensure predictable lead times. Our factory operates with dedicated material warehousing, multiple stamping and forming lines, and automated assembly to maintain production efficiency. We communicate production progress regularly and address any potential delays proactively.

For standard products, the typical lead time is 7–15 days depending on order quantity. For OEM or customized products, the lead time is usually 15–30 days, depending on complexity, tooling requirements, and production scheduling. We provide a clear production timeline before order confirmation.

We use standardized processes, controlled tooling, and consistent raw material sourcing to maintain batch-to-batch consistency. Our in-house quality inspection includes random sampling and comparison against approved reference samples. This approach minimizes variation and reduces installation or after-sales issues for our customers.

Yes, we can provide SGS test reports, salt spray test results, material certificates, and final inspection reports upon request. If your project requires specific third-party testing or certification, we can arrange this and include the documentation with your order.

Our hardware products undergo multiple quality tests including salt spray testing for corrosion resistance, life-cycle testing for durability and repeated use, dimensional tolerance checks for installation accuracy, and surface finish inspection for visual consistency. Specific test reports can be provided upon request.

Quality control is built into every stage of our production process — from incoming material inspection to in-process checks and final inspection before shipment. We perform tolerance management, salt spray corrosion testing, life-cycle testing, and visual inspection on every batch. All products must pass our internal QC standards before leaving the factory.
