Types of Sheet Metal Products
Sheet metal products come in all shapes and sizes, but three categories are absolute staples for hardware suppliers: brackets, enclosures, and panels. These are the go-to items for construction crews, electronics manufacturers, and automotive shops. Each has its own production process, cost structure, and stocking strategy. Let’s take a closer look.
Brackets for Construction
Brackets are like the trusty sidekicks of the construction world—small, simple, and indispensable. Whether it’s a basic L-bracket holding up a shelf or a heavy-duty angle bracket securing a steel beam, these pieces provide strength and stability. Research from 2023 in the *Journal of Manufacturing Processes* points out that brackets are being designed to be more modular, meaning they can fit multiple jobs without needing custom tweaks.
How They’re MadeMaking a bracket is pretty straightforward, but it takes precision to get it right:1. Pick the Material: Most brackets are made from mild steel or stainless steel, usually 1-3 mm thick. Stainless steel grade 304 is a favorite for its rust resistance.2. Cut the Shape: A laser cutter or CNC punch slices the metal into flat pieces. Laser cutting is great for intricate designs, hitting tolerances as tight as ±0.1 mm.3. Bend It: A press brake folds the flat piece into the right shape, often a 90-degree angle for L-brackets. Modern machines with computer controls nail the angles every time.4. Finish It Up: A powder coating or galvanizing (a zinc dip) protects against rust. Galvanizing is key for outdoor brackets.5. Check Quality: Inspectors measure dimensions and scan for rough edges or cracks to ensure every piece is up to snuff.
What They Cost- Material: Mild steel runs about $0.80-$1.20 per kg, while stainless steel 304 is $2.50-$3.50 per kg. A standard L-bracket (100 mm x 100 mm, 2 mm thick) uses roughly 0.2 kg, so that’s $0.16-$0.70 for materials.- Labor: Cutting and bending take 2-3 minutes per bracket. At $20-$30 per hour, labor adds $0.67-$1.50 per piece.- Equipment: Laser cutters ($100,000-$500,000) and coating setups add pennies per bracket. Powder coating might tack on $0.20-$0.50.- Total: You’re looking at $1.03-$2.70 per bracket, depending on material and finish.
Real-World Examples- Shelf Brackets: Retail stores love powder-coated mild steel L-brackets for display shelves.
