Company Profile
Who We Are
Shanghai Yizhuang Metal Co., Ltd. is a practical, hardworking company based in Shanghai, China. We are a combined manufacturing and trading business, which simply means we make our own metal hardware products in our own factory, and we also handle all the export and shipping directly. Because we do both the making and the selling, we can keep our prices fair, control the quality from start to finish, and talk to our customers without any middlemen getting in the way. We've been in the hardware business for years, and we know what it takes to deliver good products on time.
What We Make
We focus on making useful, reliable metal hardware. Our main products include stainless steel strips, custom metal stamping parts, hinges, handles, and other hardware used in construction, furniture, and everyday machinery. We use good quality materials like 304 and 316 stainless steel because we know our customers need parts that won't rust easily and can handle daily wear and tear.
Our factory has the right machines to get the job done, whether you need a huge order of standard parts or a smaller batch of custom-made pieces. We handle everything in-house: Cutting, shaping, polishing, and packaging. We don't just push buttons; Our workers and engineers actually pay attention to the details. If a batch of products doesn't meet our standards, we fix it before it ever leaves the factory. We want our customers to open the boxes and find exactly what they ordered, in good condition.
How We Work with Customers
We treat our customers like real partners, not just order numbers. Our sales team speaks English and understands how international business works. When you send us an inquiry, a real person will reply and try to understand exactly what you need. If you have a drawing or a sample, we can look at it and tell you honestly if we can make it, how long it will take, and what it will cost.
We offer OEM and ODM services. If you want your own logo on the products or need a slight change in the design, we can usually make it happen. We also know that shipping can be a headache, so we help arrange the logistics from our factory to your port. Since we are in Shanghai, we have easy access to one of the biggest ports in the world, which makes shipping faster and usually cheaper.
Keeping Things Simple and Honest
We don't like to overpromise. If a custom order is going to take three weeks instead of two, we will tell you upfront. We believe in being honest about lead times, pricing, and what our factory can actually do. We also care about running a clean and safe factory. We recycle our metal scraps, try to save electricity where we can, and make sure our workers have a safe place to work. It's just the right thing to do.
Let's Work Together
We are always looking to make good connections with buyers, wholesalers, and project managers around the world. Whether you need a reliable supplier for standard hardware or need help developing a new custom part, we are ready to help. We might not be the biggest factory in China, but we are one of the most reliable and easiest to work with.
If you have any questions or want a quote, just send us an email or give us a call. We'd be happy to chat about how we can support your business. At Shanghai Yizhuang Metal, we keep things simple: Good products, fair prices, and honest communication.
