Custom fabrication projects typically involve selecting a sheet material that is suited to the design, working conditions, and production processes involved in the project. Stainless steel sheets are available in a range of grades, thicknesses, finishes, and sizes, and there are additional requirements to consider when ordering a sheet of material for a fabrication project, beyond selecting a size. Having a thorough understanding of the requirements aids in avoiding material shortages and unnecessary costs and fabrication setbacks.
A stainless steel grade selection should be based on an assessment of the project’s material requirements. Some steel grades resist corrosion and moisture better than others while certain stainless steel sheets are easier to work with during bending, fabrication, or welding. Wherever possible, select a stainless steel grade that suits a fabrication project’s internal environment. This means the fabricator should avoid using a material with a high level of corrosion protection on an internal component, unless there are unique circumstances. Where a fabrication project is exposed to chemical compounds, outdoor exposure, salinated environments, and extreme heat, there are other steel grades with enhanced forms of corrosion resistance and superior weldability.
Fabricators must consider the manner by which a sheet of stainless steel must be fabricated to ensure a suitable grade is on order. Some grades are ideally suited to a specific fabrication technique and not necessarily suited to other production methods. A material selection that is ideally suited to one type of production might not be viable when another production process is applied. Fabricators should thoroughly understand the production requirements and how they might impact on the selection of material grade. In this manner, the fabricator avoids using stainless steels that are unnecessarily difficult to machine, bend or weld.
Another important measure to consider in relation to stainless steel sheets is material thickness. In some cases the thickness is specified by the fabrication project’s engineering parameters. In other words, the thickness must be related to the strength, flexibility, and weight of an end component that is designed during a custom fabrication project, as opposed to simply selecting the thickest sheet that is readily available. On the other hand, the production process might have specific requirements with respect to the thickness of a sheet. It is, therefore, always important for a fabricator to be fully aware of the production process requirements before selecting a material thickness.
If the thickness and material width are specified, there may need to be additional factors considered. The fabricator should always ask whether the specified sheet can be bent appropriately, taking account of the bend allowances and bending equipment that may be appropriate for the bends on a component. Additionally, when selecting a material thickness for a fabrication component, it needs to match the equipment and production techniques in terms of the cutting, forming, and marking technology.
Material dimensions play an equally vital aspect when looking to buy stainless steel sheet metal online. The fabricator must take account of the length and width of a component, plus additional allowances for cutting, trimming, and bends that have been specified in a fabrication order. This assists the purchaser in identifying suitable dimensions prior to receiving fabricated components, while also ensuring that material orders are cost effective.
Fabricators should identify standard lengths and widths that match the production requirements. Selecting a standard length or width that matches the fabrication or project requirements is likely to be more cost effective than ordering a special size if other components can be cut from the material ordered.
The surface finish of a stainless steel sheet is also crucial to the production process and end products. Where finishes play a crucial role in determining a fabricated component’s appearance, it makes sense to carefully consider the type of stainless steel that will be ordered. As a rule of thumb, the standard finish for stainless-steel sheets varies according to roughness and gloss, and different finish types offer different functions in relation to a fabrication process. If a fabricated component has additional requirements for other components that will be applied to the stainless-steel material, a finish might also be specified.
A specific finish could also be ideal when the fabricator wants to reduce the visibility of fingerprints and scratches of fabrication tools during bending, marking, cutting, or other processes involved in a stainless-steel fabrication project. When ordering a stainless-steel sheet for visible, architectural, commercial, or decorative components, the finish should always be specified in a material order to ensure that a buyer receives the appropriate type of stainless-steel sheet.
Prior to ordering a sheet of material, the buyer must conduct a detailed evaluation of an online supplier’s specifications. Information such as material-grade specifications, material thickness, sheet size requirements, surface finish specifics, tolerances, and relevant certifications, where appropriate, can provide valuable information in regard to whether a material order meets the production requirements of a fabrication project. This holds particularly true when purchasers consider buying stainless-steel sheet metal online, where ordering details and product-specific information should be given particular attention prior to placing an order for material.
It is also important for purchasers to consider the packaging of a purchased material, particularly when material sheets are fragile and prone to scratching or other damage. With larger scale fabrication projects, the delivery requirements may also influence a purchaser’s selection process. Having this information at hand can assist in ensuring material arrives in good condition and is ideally suited to the next stage in a fabrication project.
Thinking of buying stainless steel sheet metal online is likely to result in substantial production advantages to a fabricator. At the very least, planning results in ensuring that a purchasing order follows material specifications, including stainless-steel grade, sheet thickness, surface finish, sheet dimensions, quantity, and relevant certifications. Double checking of the order is likely to prevent any order mistakes which could potentially cause a fabrication setback.
Finally, good order planning takes account of future production orders. If multiple components will require similar materials, it may make sense to order sheets of compatible stainless-steel grades in a manner that facilitates consistent manufacturing processes across multiple projects.
