Allegeni Stainless Steel

Stainless steel materials make up the huge bulk of construction and building materials in this day and age. From exteriors to interiors, stainless steel sheets, bars, seamless and sanitary tubes and pipes have become indispensable in modern business. The long-lasting qualities of stainless steel more and more make it a smart investment.

What’s quite unique about this industry is the production network of steel producers from primary to intermediate to finished steel products. Dynamism in each of the levels of the production network is important, especially when the success of the industry relies on the performance of both the steelmaker and steel-user.


We recognize that while difficult choices must often be made between implementing green solutions and implementing cost effective materials, Sanyo Seiki has demonstrated that it can offer both. Through the years, we have seen the long-lasting quality after ensuring the right stainless steel grade is selected to match the corrosion conditions of the environment and after applying the correct cleaning and storage methods.

Sanyo Seiki is the top producer of stainless steel in the Philippines for the major steel end-users. Our brands, Allegeni stainless sheets and plates and Smith Muller stainless pipes, tubes and bars, are the market leaders.
