Foshan Dongyuan Trading Co., Ltd. is a company dealing with a variety of products, whose major products are stainless steel and related accessories such as stainless steel valves, sculptures of all kinds of shapes as well as spheres covering many sizes. Having been in this trade for 4 years, we have succeeded in satisfying our clients and customers throughout the world for our products are of excellence and superiority. Customers’ needs are always our priority. Please rest assured that once we start meeting your requirements on any possible products we could come up with, no worries will incur about the quality, prices and all sales services. We are accountable and obligated for our customers’ comfort in terms of product quality, service and after-sales.
We are capable of providing stainless steel spheres/balls almost as per your specific requirements. Products include hollow stainless steel spheres (ranging from 6mm to 2500mm in diameter), available for delivery if we have it in stock or delivered within 15 days. Wall thickness of spheres varies from 0.4mm to 3mm. Shaped by water pressure, our products could be mirror polished without any seams noticeable on the surface; meanwhile, welding and then sandblasting spheres is a another way to produce mirror polished spheres also without detectable traces on the spheres. Having been offering services for our customers worldwide, a variety of products also fall under many categories of our products. Staidness steel spheres, hollow or solid, of all sizes are our major products, and brass and bronze balls come along. Hollow reflective stainless steel spheres of enormous sizes are amongst the top sales in our products. Perforated stainless steel spheres or sculptures of 304 or 316 are also our hot products. Not to mention we have done considerable amount of drilled stainless steel balls or spheres with holes of many sizes. Our products are of professional and advanced technology with cost-effective craftsmanship and favorable delivery time.
A:Yes, we offer a wide range of options to meet different requirements from our clients regarding size/diameter, thickness, color and material and so on. Options include: stainless 304 and 316 or 201, powder coat, paint, galvanized plate, or natural rust finish. Our powder coated finish has an undercoated zinc plate for outdoor use, which also eliminates the need for maintenance and rusting.
Q:What is your lead time?
A:Our general lead time is 10-15 days but may extend during peak periods.
Q: If I re-size your designs, is there a price change?
A:In most cases, varying the design will result in minimal variations in price. Customising would mean the cost of creating a new template, changes in laser cutting time, and re-formatting our machines usually contributes to a re-size fee.
Q: Do you customize?
A:Yes, the majority of our business is either using our in-house designs, or further developing your own designs presented to us. We can modify by re-scaling, re-sizing, adding signage / script etc.
Type 304 Stainless Steel is a variation of the base 18-8 grade, with a higher chromium and lower carbon content. The lower carbon content minimizes chromium carbide precipitation due to welding and its susceptibility to intergranular corrosion. In some instances Type 304 can be used in the "as-welded" condition. Type 304L is an extra low-carbon variation of Type 304 with a 0.03% maximum carbon content that eliminates carbide precipitation due to welding. As a result, this alloy can be used in the "as welded" condition, even in severe corrosive conditions. In many cases it eliminates the necessity of annealing weldments except for applications specifying stress relief. Type 304L has slightly lower mechanical properties than Type 304. High strength, excellent corrosion resistance and excellent formability make Types 304 and 304L Stainless Steels useful for many applications. Typical uses include architectural moldings and trim, kitchen equipment, as well as chemical, textile, paper, pharmaceutical and chemical industry processing equipment.For severely corrosive environments or when welding is required, Type 304L is preferred because of its greater immunity to intergranular corrosion.
