Base Construction, Inc. has worked on a wide range of structural steel fabrication projects. We have designed and built Process Piping Structural Steel Supports, Pipe Bridge, Slope Tanks Bottom Support, Tank Anchoring Support Systems, Structural Steel Foundations, Support Foundation for all types of equipment, Handrails, Platforms, Catwalks, Ladders, Plate and Structural Steel Fabrication, Machine Guarding, and Structural Steel Repair and Restoration. Along with the design process, we can safely install all structural steel systems we design for your project while staying within budget and schedule limitations. We can design and estimate a project ahead of time for customer, for their next year or two budgeting, and work with them along the way to accomplish that.

Stainless steels are selected for food contact application because they are resistant to corrosion, inert, easily cleaned and sterilized without loss of properties, and can be fabricated by a variety of techniques into robust structures. The selection of an appropriate stainless steel grade is critical to the success of any food contact application. It is vital that all aspects of the application are considered in the grade selection process (eg cleaning regimes, their associated chemicals and whether operation of the plant will be continuous or batch-type with shutdowns). In the majority of food contact applications where stainless steel is used, austenitic grades with 18% chromium provide an optimum balance of corrosion resistance (to a wide range of foodstuffs), cost and ease of fabrication. Nevertheless, ferritic, martensitic and duplex stainless steels are also used in food contact applications. Figures 1 to 4 illustrate typical food contact applications where austenitic, ferritic martensitic and duplex stainless may be used.  Martensitic stainless steels may be hardened by heat treatment and are suitable for moderately corrosive environments. For example, medium-priced cutlery often utilises grade 1.402 (AISI 420), while grade 1.4122 with a higher carbon content and molybdenum tends to be used for high quality cutlery and grade 1.4116 with high carbon, molybdenum and vanadium is used for cooks’/professional knives.  Ferritic stainless steels offer good corrosion resistance, but cannot be hardened by heat treatment and have limited formability. Typical applications for grade 1.4016 (AISI 430) include low-priced cutlery, hollowware, work surfaces and cabinets, and trim on domestic cookers.
