Powder coating or plastisol

Every roller shutter door we manufacture leaves our Sunderland factory finished in one of two ways: powder coating or plastisol. Both are durable, both protect the metal, and both are available in a range of colours. The right choice depends on your application and the colour you want.

Which finish is right for your door?

Both finishes are manufactured and applied at our Sunderland factory, so whichever you choose, your door ships with the same build quality and the same warranty.

    Powder coating

    £28 per square metre (ex VAT)

    Powder coating is an electrostatic process. Dry paint powder is applied to the metal surface then baked in an oven at high temperature. The result is a hard, smooth finish that bonds directly to the metal.

    It's the more durable of the two options. Powder coating resists chipping, fading, and corrosion well, and handles impact better than plastisol in most conditions. It's also the better choice if you want a specific RAL colour — the range available is far wider than plastisol

    Plastisol

    £15 per square metre (ex VAT)

    Plastisol is a PVC-based coating applied as a liquid and heat-cured to form a flexible, textured finish. It's been the standard finish on roller shutter doors for decades and remains a reliable, cost-effective option.

    The finish is slightly textured rather than smooth. It's available in a defined range of Masterline colours rather than the full RAL range. Within that range it performs well and the colour holds over time.

Which should you choose?

For most domestic garage doors, plastisol is the practical choice. The standard colours cover white, black, anthracite, and brown, and the price difference is meaningful across a full door.

Choose powder coating if you need a specific RAL colour outside the plastisol range, want a smoother finish, or need maximum long-term durability. It's the standard choice for commercial shutters on customer-facing or exposed elevations.

Box type

We offer two different box types for our domestic doors:

Full box

  • The Look: Completely encloses the roll in a sleek aluminum housing.
  • The Benefit: Protects the motor and curtain from dust, grit, and nesting birds. It’s also a vital safety barrier if you use your garage for storage or as a workshop.
  • Verdict: Choose this for a "clean" professional finish and maximum longevity.

Half box

  • The Look: An L-shaped fascia that covers the front and top. The back of the roll remains visible from inside the garage.
  • The Benefit: Saves on cost while still providing a neat appearance from the driveway.
  • Verdict: Best if you are on a budget and don't mind seeing the mechanism from inside the garage.

How to measure for your door

We manufacture your door based on the "Daylight" size (the actual hole in the wall). Measurements must be taken viewing the opening from the inside looking out.

Step 1: The Width

Measure the width between the brickwork at the top, middle, and bottom. Use the narrowest measurement.

Step 2: The Height

Measure from the internal floor to the underside of the lintel. Ensure the floor is level.

Step 3: Right space

Measure space from opening to the first obstacle.

Step 4: Left space

Measure space from opening to the first obstacle.

Step 5: Headroom

Headroom from the start of the lintel and lowest part of the ceiling.

Option B - Reveal fix

Option C - Combination fix, face and reveal fixing

Option D - Undersize fix

Clearance requirements

  • 77mm Slat: Needs 300mm above the lintel.
  • 55mm Slat: Needs 205mm above the lintel.
  • Sideroom: You need 90mm on each side for the guide rails for fixing behind the openings

Side profile

Please note that when the roller door is fully open, the bottom slat will always hang down by approximately 70mm from the top of the guide rails.
