Company Profile
SMLSCO has been involved in the stainless steel seamless pipeline system industry since 2006. After 17 years of development, SMLSCO has achieved an excellent reputation in the industry by supplying good quality materials with considerate service.
With the passage of time, we have gradually expanded our product line according to the needs of our customers, which now includes Pipe, Tube, Stainless Steel Flanges, Stainless Steel Forged & Casting Fitting.
We shorten lead times by reducing costs through inventory. For PIPE and TUBE, as the production cycle is very long, we stock finished products. For FLANGE and FITTING, although the lead time is short, there is a shortage of blanks which affects lead time and order cost, so we choose to stock the raw material of FLANGE and FITTING - blanks.
Whether it is PIPE & TUBE, or FLANGE & FITTING, SMLSCO is committed to providing customers with more (more sizes, more categories), faster (quicker lead time), better (qualified products), and more cost-effective pipeline system products.
