Sheet metal is the most versatile stock material in manufacturing: almost anything that has a wall and a shape can be made from it. Here are the products ordered most often — and how to make a design cheaper while it is still just an idea.
What It Is Used For
- Enclosures and covers for equipment, electrical cabinets, machine tools, generators. The most common category: a box shape, ventilation openings, doors.
- Cable trays, ducts, gutters — simple in shape but demanding when it comes to length accuracy and repeatability.
- Brackets, mounting plates, angle pieces — small parts that are almost always made in production runs.
- Facade cassettes, parapets, flashings, soffits — here the priorities are a flat surface with no waviness and a clean edge.
- Boxes, cabinets and safes — storage for tools, documents and firearms: a sheet metal body, a reinforced door, a lock.
- Furniture frames and retail equipment — racks, shelves, stands, display elements.
- Decorative perforated panels — screens, fences, air conditioner covers.
Why a Bent Part Beats a Welded One
The same box can be made in two ways: cut five plates and weld them together — or cut one flat pattern and bend it. The second route almost always wins.
A bent part is stronger, because it has no seams in the corners — and the seam is the weakest point of any structure. It is more accurate, because the angles are set by the press brake, not by a welder's hand. It is cheaper, because welding and subsequent seam grinding cost more than a few bends. And it looks neater, which matters for anything that stays in plain sight.
So when designing a product, it is worth asking yourself: can this part be made from a single piece of metal? Very often the answer is yes.
What Makes a Product Cheaper
- Fewer different thicknesses. If the whole product can be made from one sheet, you save both on material and on machine changeovers.
- Identical bend radii. Different radii mean a tooling change — that is time.
- Simple holes instead of ornate cutouts. A round hole cuts faster than a complex contour with fine details.
- Precision only where it is needed. Tight tolerances along the entire contour make the part more expensive, while usually only two or three dimensions are critical.
- A production run instead of one-off orders. Setup is done once, so ten parts cost much less than one part ten times over.
Where to Start If All You Have Is an Idea
A drawing is not required. A dimensioned sketch, a photo of a similar product or a sample to replicate is enough. More important than the drawing is understanding three things: what the product must withstand, where it will operate and how many pieces are needed. From this, an engineer will select the metal, thickness and technology.
A typical route for such a product through our workshop: laser cutting of the flat pattern → bending → welding if needed → powder coating. Describe your task through the form — we will suggest a solution and calculate the cost.
