Frequently Asked Questions

For orders, it is bank transfer or letter of credit. We do not take credit cards directly. For small samples or quotes, we can arrange payment through our partners. Typical terms are 30% deposit, 70% before shipment. If we have worked together for a while, we sometimes open account terms.

316 is the same as 304 but with molybdenum added. That makes it handle salt water, acids, and harsh chemicals much better. It is used in marine environments, food processing with salts, and chemical plants. It costs more, so only use it where 304 will not hold up.

We use a spark spectrometer to verify chemical composition on every batch before it leaves the factory. The MTR documents it. If you want, we can also provide XRF analysis or send samples to your own lab for verification. Transparency matters.

We prepare all the export documentation — invoices, packing lists, certificates of origin, and material test reports. Customs clearance at your destination is your responsibility, but we work with freight forwarders who can help arrange DDP if you need it. Just tell us what you need.

Every shipment comes with an MTR — chemical composition, mechanical properties, dimensions, all verified. For 304 and 316, it shows the exact nickel and chromium content. You can trace every piece back to the mill if needed.

It depends on the product. For standard sheets and coils, we can go as low as 500 kg. For tubes and fittings, usually around 1 tonne. Special grades or custom sizes may raise that higher. Just tell us what you need and we will give you a number — no pressure.

It depends on where you are and what we are shipping. Within China, a few days. To main ports in Southeast Asia, about two weeks. Europe and North America typically 25-35 days by sea. Air freight is faster but costs more — we always show both options so you can decide.

Very likely. We work with mills that produce custom gauges. The lead time might be a little longer and the price slightly higher, but we have handled special sizes before. Send us your specifications and we will check with our suppliers.

We handle a lot in-house. CNC bending, punching, welding, polishing — the usual. If it is too specialized, we have partner workshops that handle it. One point of contact, multiple capabilities.

Duplex grades like 2205 and 2507 are the heavy hitters. Twice the strength of 304, much better corrosion resistance, especially against pitting. Used in oil and gas, chemical processing, and offshore work. They cost more per kilogram but you often use less material because they are stronger.

We replace it. No arguments. That is our policy. We inspect everything before it ships, but if something slips through, we fix it fast and at our cost. Long-term business depends on trust, and trust depends on standing behind what you sell.

Yes. We can send samples of standard grades quickly. Custom products may take a little longer. Samples usually have a small cost, but it gets deducted from your first order. It is better to test than to guess.

Yes, that is exactly what we do. Send us your requirements — grade, dimensions, quantity, surface finish — and we will respond usually within 24 hours. No commitment. If the price does not work for you, you know and we part ways cleanly.

Yes. 430 is a ferritic grade — magnetic, cheaper than austenitic steels, with good corrosion resistance for less demanding environments. Ideal for automotive trim and some kitchen equipment. It does not weld the same way as 304 or 316.

That is what we are here for. Tell us what the part does, what environment it will be in, how much load it supports, and we will recommend a grade. Sometimes the obvious choice is not the right one — and sometimes a cheaper grade works perfectly fine. We will tell you.

Yes, much more than most people realize. Smoother finishes resist corrosion better because there is less surface area for moisture and contaminants to stick to. A mirror finish on a 316 plate will last longer than a No.4 finish in the same environment. A cheap finish on good steel is not always cheap.

304 is the standard grade for most food and construction work. It has good corrosion resistance, is easy to weld, and is reasonably priced. If you are not sure what you need, 304 is usually the safe bet. It is not great for anything very salty.

Of course. Tell us what you are building, what environment it will be in, and any mechanical requirements. We will recommend the right grade for you. It saves money in the long run — nobody wants to replace a part that corroded in six months.

Yes. We have laser cutting, plasma cutting, and shearing for different thicknesses. Tolerances are typically ±0.5 mm for laser cuts. We can make complex shapes, not just straight cuts. Send us a drawing and we will tell you if it works.

Send an email to our technical support address, or ask your sales representative to connect you. You can also call our technical hotline for urgent questions. We respond in English and Spanish, and our engineers understand the real problems you face on the shop floor.

Sure. We can print your company logo, add custom labels, or use your preferred packaging. It does not change the price much, and it makes life easier for your receiving team. Just tell us what you need.

2B is our default — matte, good for most industrial uses. No.4 is the brushed finish that is popular for appliances and architectural trim. Mirror finish when you need that polished glass effect. BA gives you a shiny surface straight from the mill without extra polishing. We can also do hairline.
