DIY Football Goal: Build Your Own Goal in a Few Steps

Reading time approx. 7 minutes

Building your own aluminium football goal is the perfect solution for your garden, training, or leisure time. Instead of expensive ready-made goals, this guide provides you with a stable, durable, and customisable goal – exactly to your needs.

With aluminium system profiles (40x40 Slot 8), you can build a modern, rust-proof football goal that is easy to assemble and will last for many years. In this step-by-step guide, we'll show you what to look out for, what dimensions are suitable, and what materials you'll need.

  DIY saves costs: Building your own is often cheaper than ready-made goals and more flexible in size.

Planning & Dimensions for Your Aluminium Football Goal

Before you build your own football goal, you should decide on the appropriate size. For garden and leisure use, the following dimensions are common:

• 3.00 × 2.00 m – classic leisure goal
• 5.00 × 2.00 m – youth category
• 7.32 × 2.44 m – official full-size pitch goal

In this guide, we focus on a 3 x 2 meter aluminium football goal, which is ideal for private use in the garden, on the training pitch, or in leisure areas.

Which Aluminium Profiles are Suitable?

For construction, we recommend 40x40 Slot 8 system profiles. These profiles are stable, modular, and can be easily screwed together with suitable accessories.

• high stability with low weight
• easy assembly with brackets, T-nuts, and screws
• flexible expandability
• rust-proof and weather-resistant

The connection is made either via angle connectors, T-nuts, and screws or alternatively via a centering plate set – entirely without welding.

Material List for a 3.00 m × 2.00 m Football Goal

• 3 × Aluminium profile 40x40 Slot 8 of 3,000 mm each – front top, back top, and back bottom
• 4 × Aluminium profile 40x40 Slot 8 of 1,920 mm each – vertical posts
• 2 × Aluminium profile 40x40 Slot 8 of 920 mm each – side depth top
• 2 × Aluminium profile 40x40 Slot 8 of 960 mm each – side depth bottom
• 12 × Angle connector set 40x40 or alternatively 12 × Centering plate set
• 1 × Goal net as required
• Cable ties or hooks for attaching the net
• Optional: 4 × End caps 40x40

The front lower crossbar is intentionally omitted. This leaves the goal open at the front and allows it to be used like a classic football goal.

If the finished goal is to be exactly 2,000 mm high on the outside, the vertical posts must be correspondingly shorter due to the 40-mm profiles at the top and bottom. This results in a post length of 1,920 mm.

Tools Required

• Allen key
• Wrench
  
• When using centering plate sets: Drill and tap
• Optional: Rubber mallet for end caps

Connection Comparison: Angles vs. Centering Plate Set

When building your aluminium football goal, you have two options: classic angle connectors or a centering plate set. Both variants have their advantages – depending on whether you prefer a simple DIY solution or a particularly clean professional connection.

Conclusion: Angle connectors are ideal for quick DIY projects. For maximum stability, durability, and a clean appearance, we recommend the centering plate set.

Build Your Own Aluminium Football Goal – Step by Step

The assembly of your DIY football goal is done in several steps. Work as much as possible on a flat surface and regularly check the angles to ensure the frame remains perfectly rectangular.

1. Assemble the Front Frame

First, assemble the front frame. This consists of the upper 3,000 mm profile and two vertical posts.

• Lay out the profiles on a flat surface.
• Align the posts at a 90° angle to the upper cross profile.
• Screw the connections with angle connectors, T-nuts, and screws.
• The lower front crossbar is intentionally omitted so that the goal remains open at the front.

2. Build the Rear Frame

The rear frame provides stability and will later hold a large part of the net attachment.

• Build the rear frame from an upper and a lower 3,000 mm profile and two vertical posts.
• Again, ensure exact 90° connections.
• Initially tighten all screws lightly, align the frame, and then tighten them definitively.

3. Connect Front and Rear Frames with Side Sections

Now connect the front and rear frames with the side profiles.

• Insert the 920 mm profiles at the top between the front and rear frames.
• Insert the 960 mm profiles at the bottom, as no lower crossbar is installed at the front.
• Screw the side sections with angle connectors or centering plate sets.
• Ensure that all profiles are flush at the corners.
• Then check if the goal is straight and not warped.

4. Attach the Net

The goal net is attached to the front and side frames.

• Lay the net evenly over the back, sides, and top.
• Attach it to the profile with cable ties or suitable hooks.
• Tighten the net only slightly so that it is not unnecessarily under tension.
• Neatly trim any excess cable ties.

5. Optional: Mount End Caps

Finally, you can close the open profile ends with end caps. This provides a clean appearance and increases safety.

End Caps – Function & Advantages

End caps for aluminium profiles are placed on open profile ends. They are optional but particularly useful if the football goal is used in the garden or leisure area.

• Protective function: They prevent dirt, water, or insects from entering open profile ends.
• Safety: Open edges are covered, reducing the risk of injury.
• Appearance: The goal looks cleaner and more professionally finished.
• Durability: The profile ends are better protected from dirt and moisture.

The end caps can be easily and quickly attached to the profiles. To do this, the caps are inserted with the central pin into the through-hole of the structural profile.

If manual force is not sufficient, a light, gentle tap with a rubber mallet can help to fit the plastic cover flush into the profile.

Advantages of an aluminum soccer goal

• Rust-free & weatherproof – ideal for outdoor use
• Durable – significantly more durable than wood
• Lightweight – easier to move than many steel constructions
• Modular – expandable or adaptable at any time
• No welding required – all connections are screwed

Compared to wood, aluminum is much easier to maintain and remains stable even in rain and humidity. Furthermore, an aluminum profile soccer goal can be disassembled, expanded, or repaired if necessary.
