Hvor kan man købe 80 20 aluminiumsprofiler?

Looking for 80/20 aluminum extrusion and not sure where to buy? Many choices exist, and picking the right supplier can be confusing.

You can buy 80/20 aluminum extrusion from specialized extrusion companies, online distributors, general metal suppliers, or even custom extrusion manufacturers.

In the rest of this post I show which suppliers offer 80/20, why you might compare 80/20 with alternatives, how to pick correct series, and how accessories can widen your options.

Which suppliers stock 80/20?

Need reliable flow of aluminum extrusions? Some suppliers stand out.

Suppliers who stock 80/20 include dedicated 80/20‑style extrusion brands, industrial metal distributors, and custom aluminum extrusion producers that hold standard profiles in inventory.

When you search for 80/20 aluminum extrusion, first look at suppliers who specialize in modular framing. These often carry the standard T‑slot profiles such as the typical 1.5” x 1.5”, 1.5” x 3”, 2” x 2”, 2” x 4”, and larger series. They keep stock profiles ready for cut-to-length orders.

Then there are general metal distributors. They may carry aluminum bars, sheets, tubes, and sometimes modular extrusion profiles. Their stock may not include the full range. But if you only need a few standard pieces, these distributors can be a good option.

Another group is custom extrusion manufacturers that normally make custom shapes for heavy industry. Some of them keep common modular profiles in stock or can mill them upon request. These firms tend to serve B2B clients, often in larger volume. They can cut, drill, or anodize the extrusions before shipping.

Often price and lead time vary a lot across these types of suppliers. Specialized modular-framing suppliers tend to be easiest for small projects or prototypes. Metal distributors might offer lower per-foot cost when you order long lengths, but they may not cut for you. Custom manufacturers give flexibility on cut, finish, and custom sizes — but often need bigger orders or minimum order quantities.

Here is a comparison of typical supplier types:

In my view, if you need just a few cut-to-size pieces, go for the first group. If you need long lengths or bulk raw extrusions, the second group can work. If you need custom sizes or finishes, the third group is worth contacting.

Why compare 80/20 vs alternatives?

Maybe 80/20 is strong. Maybe other options fit better. Good to compare.

Comparing 80/20 extrusion with alternative framing systems or raw aluminum helps you find the best balance of strength, cost, flexibility, and availability for your project.

Using 80/20 aluminum extrusion has clear benefits. It offers modular assembly, T‑slot flexibility, and easy reconfiguration. You can bolt parts together without welding. That saves time and gives flexibility when you need to adjust or expand. Also the standard profiles often meet strength needs for frames, enclosures, light machinery, or fixtures.

Yet sometimes alternatives may serve you better. One alternative is raw aluminum as plate, bar, or tube. If you need a part with custom shape or solid wall thickness, raw aluminum gives more freedom. Raw pieces can be machined or welded to shape. But raw aluminum often means more work — you need cutting, drilling, welding, or machining.

Another alternative is welded steel framing or mild steel. Steel can yield higher load capacity, but added weight and possible rust are downsides. Steel also often needs welding or surface protection.

Also there exist other modular framing systems beyond 80/20‑style extrusion. These systems may use different slot shapes or fasteners. Sometimes they cost less, but they might not have as wide a range of accessories. Also fewer suppliers carry them globally.

When you compare 80/20 versus alternatives, think about: project scope (small vs large), budget (material cost vs labor cost), time (assembly vs machining), strength needs, and future adjustability.

If you need a flexible frame that may change, 80/20 is often best. If you need a heavy duty welded frame or a custom shaped part, raw aluminum or steel may fit better.

How to select correct 80/20 series?

Using the wrong series can cause weak frame or waste money. So choose carefully.

You select the correct 80/20 series by matching profile size, slot width, wall thickness, and load requirements to your design and use case.

First decide what you build. For light jigs or simple enclosures, small profiles like 1.5" x 1.5" or 1.5" x 3" are often enough. These are lighter, easier to handle, and usually cheaper per foot. But these smaller profiles have lower load capacity and weaker resistance to bending or torsion.

If you build heavier frames — like machine guards, workbenches, or structural supports — then larger profiles like 2" x 2", 2" x 4", or even larger may be needed. The extra material and wall thickness help resist bending and maintain rigidity.

Another factor is slot width and fastener compatibility. Many 80/20 style systems use standard T‑nut and bolt fasteners sized for specific slot widths. If you pick a profile with a slot too narrow, some hardware may not fit. If you pick too wide, you may need different fasteners which cost more. So check fastener specs before you order.

Also know that extrusions come in different wall thicknesses or strength grades. Some series are rated for heavier loads; others are meant for light duty. If you expect your frame to carry heavy weight or dynamic loads, choose series with thicker walls or reinforcement ribs.

Length matters too. Most suppliers offer full length (e.g. 96 inches, 2400 mm) and cut‑to‑length. If you choose cut‑to‑length, cut fees or wastage may affect cost. For long spans or long linear frames, you may need continuous extrusion without joints for strength.

Finally consider surface finish and corrosion resistance. If the frame will be used outside or in humid environments, choose anodized or powder‑coated finish. These finishes protect aluminum and extend life.

In short, map your build needs — load, size, fasteners, finish — to the profile. Doing that avoids weak frames or wasted money.

Can accessories expand 80/20 use?

Accessories might seem small. But they multiply the ways you can use 80/20.

Accessories like corner brackets, joint plates, T‑nuts, end caps, wheels, panels and hinges expand the usefulness of 80/20 frames, letting you build tables, cabinets, guards, carts, enclosures, and more.

Once you get the base aluminum extrusion profiles, the right accessories let you build many kinds of structures. For example, corner brackets or joint plates help you form rigid right-angle frames. These make boxes, racks, or machine guards easy.

T‑nuts and bolts are essential. They slide into the slot and secure whatever you attach. They allow you to mount panels, shelves, or other components without drilling or welding. End caps cover the open ends. They improve safety and give a cleaner look.

If you need mobility, add wheels or casters. With proper brackets, you can turn a fixed frame into a mobile cart or trolley. Panels and hinges let you build enclosures or access doors. You can mount sheet metal, acrylic, or plywood panels to the frame. Hinges help you make doors or lids.

You can also add adjustable feet, leveling pads, or vibration‑damping mounts. These accessories make your frame stable on uneven floors and reduce noise or vibration if you mount machinery.

Moreover, some accessories expand function beyond structure. For example, linear motion rails, sliders, or hinges convert your frame into moving parts or adjustable fixtures. Shelf brackets or drawer slides add storage capability. Light mounting plates or mounting rails help create assembly or workstations.

Using accessories makes the 80/20 system modular. You do not need welding. You get reuse: you can disassemble and rebuild. You get flexibility: you can expand or reconfigure. For small shops or prototyping, that can save time and cost.

Here is a table with typical accessories and their uses:

If you combine right profiles with accessories, you can build many kinds of systems: workbenches, machine guards, enclosures, storage racks, carts, test benches, custom jigs, and more. Accessories increase return on material and let you adapt over time.

Konklusion

Using 80/20 aluminum extrusion becomes simple once you know where to look, how to choose profile and series, and how to use accessories for flexible builds. Pick the right supplier, match the profile to your needs, and add the right accessories. You will get strong, modular, and adaptable structures.
