The Essence of a Sheet Metal Quote

Sheet metal fabrication involves cutting, punching, folding and assembling flat aluminum or steel sheets. Sheet metal, in particular, can be easily cut and bent into any shape, accounting for its versatility for a multitude of applications. Based on these fundamentals plus the complexity of each unique job, Prototek can provide a sheet metal quote that includes pricing and turnaround estimates.

Services Considered in Our Sheet Metal Quotes

We are driven to provide accurate and comprehensive sheet metal quotes based on the processes, machines, materials and custom components necessary to complete your job. This includes considering which of our services are necessary to get the job done. Here are the various sheet metal services we offer and consider in any sheet metal quote:

  • Manufacturing Design Assistance

    We consider the product purpose, necessary product strength, product quantity requirements, industry standards, required material qualities and other relevant factors when determining how to construct your metal components. To ensure the end product is perfect, we offer manufacturing design assistance. It benefits everyone involved to ensure the design is structurally sound before any fabrication begins. This is also where are our quoting begins. By reviewing initial designs, we can help align cost expectations.

  • Laser Cutting

    Laser cutting, in particular, is the technique of cutting materials with a high-power density laser beam. Plates that can get treated in the cold bonding and hot bonding ranges, for example, should be less than or equal to 20.0 mm thick, and stainless steel should be less than 10.0 mm thick for optimal results.

  • Punching

    Punching is a sheet metal production method in which a scrap slug is extracted from the metal workpiece each time a punch enters the punching die, resulting in a hole on the metal workpiece.

  • Material Graining

    Material graining is a technique for achieving a uniform, clean finish on the surfaces of a wide range of metals, including sheet metal.

  • Drilling – Countersinking – Tapping

    Holes can be drilled or bored, especially for flush fastener heads. Furthermore, countersunk holes can be drilled into sheet metal components so that when the product finishes, the fastening head is even with the metal. Finally, we can use tapping drills to make threaded holes in sheet metal so that fasteners can be inserted and screwed in.

  • Forming

    Forming is a type of sheet metal machining that includes processes such as bending. Cutting removes material from a sheet of metal, whereas forming just reconfigures into desired contours. Moreover, you can bend sheet metal manually or with the use of press brakes.

  • Hardware Insertion

    We have hardware insertion capabilities in-house to ensure hardware pieces can be inserted correctly, precisely and rapidly.

  • Mechanical Assembly

    From simple mechanical assemblies of fabricated sheet metal parts to sophisticated electro-mechanical assemblies with significant materials, our mechanical assembly services encompass various component assembly and integration methods.

  • TIG, MIG & Spot Welding

    Tungsten Inert Gas (TIG) welding is a method of welding in which a non-consumable tungsten electrode powers the welding arc. TIG welding gets used widely throughout stainless-steel parts, lean gauge mild steel and non-ferrous metals.

    On the other hand, MIG welding is an arc welding procedure in which a fixed feed of solid wire electrode is delivered through a welding gun and into the welding pool at a continuous rate. MIG welding works well on mild steel, stainless steel and aluminum, among other materials.

    Finally, Spot Welding combines two or more metal sheets by exerting pressure and heat from an electric current to the weld zone.

  • Welded Assemblies & Frames

    We use advanced manufacturing equipment and abilities to create assemblies and frames that combine machined parts, formed parts and welding techniques.

Standard Costs Involved with Sheet Metal Quotes

Most sheet metal quotes, as it pertains to sheet metal fabrication, take into consideration the following details:

  • Production Time

    Production time can influence your online sheet metal quote. The time it takes to produce a part using our sheet metal fabrication services is a factor we take into consideration when creating any sheet metal quote.

  • Number of Machines Involved

    Some sheet metal quotes we provide involve the use of multiple machines to complete a job. The more machines involved, the more complex your quote may be. See list of sheet metal machines we use below.

  • Shipping

    The need and distance to ship final products will definitely have an effect on the pricing and costs involved with your end sheet metal quote.

Factors That Can Affect Sheet Metal Costs and Quotes

Cutting, bending and assembling metal structures are all part of the metal fabrication process, constituting the bulk of sheet metal fabrication costs and end sheet metal quote pricing. However, there are other elements that can affect the total cost of your sheet metal project. Here are a few additional factors that can affect your sheet metal quote:

  • Materials and Processes Used

    The material and processes used constitute the biggest factors affecting the overall sheet metal quote, incurring the bulk of sheet metal price and sheet metal cost. See list of sheet metal materials to consider below.

  • Finishes Involved

    Customers can choose from various sheet metal finishing choices that reinforce parts, improve aesthetic appeal, save assembly time and provide other perks, depending on the project.

  • ITAR Requirements

    The International Traffic in Arms Regulations, (aka ITAR) are export control regulations administered by the US Department of State (DOS). These regulations are used by the Department of State to regulate products on the United States Munitions List and the Missile Technology Control Regime. This includes anything designed for military or defense-related applications. This means we must prove we are ITAR compliant before taking on any projects that fall into those categories.

    We are ITAR compliant, but with such compliance comes added costs. So, if your job requires ITAR compliance, this will be considered in your sheet metal quote.

  • Type of Inspection or Quality Reports Required

    Depending on the project, methods used and final assembly required, they may involve several inspections and quality reports to ensure each step of the process is perfect. The more inspections and reports required, the more involved your sheet metal quote may be.
