Samson garage guard steel security steel doorsets

Samson GarageGuard Security Steel Door

The Samson GarageGuard Security Steel Door is a robust, made-to-measure doorset created specifically for security-conscious homeowners who want a serious upgrade over a basic timber or single-skin metal personnel door. Designed to protect your garage, home and outbuildings, it combines double-skinned steel construction, dedicated security hardware and a clean, modern appearance that can be tailored to complement your property.

At its core is a 55mm thick door leaf with double-skinned steel construction in corrosion-resistant Magnelis® steel, providing a far stronger and more durable barrier than a typical domestic side door. Depending on the chosen infill, U‑values between approximately 3.1 and 1.6 W/m²K are achievable, delivering useful thermal performance alongside enhanced security. Stainless steel lever/lever handles are supplied as standard, with the option to upgrade furniture if required.

Designed Around Everyday Security

GarageGuard has been carefully developed around real-world domestic use, with a security protocol that supports both daytime and night-time locking. A high-security Hooply multipoint sashlock works in conjunction with a Securefast TS007-rated euro cylinder and security escutcheon, providing double locking as standard and a clear, simple routine for securing the door whenever the property is unattended.

The door is supplied fully factory assembled with its outer steel frame, so alignment and locking performance are set in the factory rather than on site. An adjustable outer frame allows for fine-tuning into out-of-square openings, making installation easier and helping to maintain long-term security performance as the building moves or settles.

Style Options for Domestic Garages

Unlike many purely functional security doors, the Samson GarageGuard can be specified with design embossing on the external face to replicate vertical or horizontal boarding. This creates the look of a contemporary timber or panelled door while retaining the strength of steel, allowing the garage access door to echo the style of main entrance doors or other architectural features on the home.

A choice of more than 50 standard polyester powder coated colours is available, including the option for a different colour inside and outside, and even a contrasting frame colour. This flexibility makes it easy to match existing windows, doors and cladding, ensuring the security upgrade enhances, rather than compromises, the visual appeal of the property.

Made-to-Measure UK-Manufactured Quality

Manufactured in the UK by Robust Doors exclusively for Samson Doors, every GarageGuard doorset is made to measure as standard and supplied ready to fit with all necessary hardware, locking and adjustable outer sub-frame. Standard sizes go up to 1085mm wide x 2195mm high, with larger sizes available on request, and the leaf is finished smooth both sides with an external astragal for additional attack resistance.

Panel infill options include a honeycomb core delivering around 3.1 W/m²K, with alternative infills available for improved thermal performance where required. The 95mm deep “C” type frame with single rebate, 15mm rebated aluminium threshold and stainless steel round-bar lever handles complete a specification that is engineered for strength, weather protection and long service life.

Installation Guide: Samson GarageGuard

The Samson GarageGuard is engineered with one clear goal: to be the easiest and fastest high-security steel door to install on the domestic market. Designed specifically for garages and outbuildings, our "Single Fix" design and adjustable frame system remove the complexity of traditional on-site joinery, making it achievable for competent DIYers and tradespeople alike.

Delivered for Speed

To minimize site time and disruption, we supply our doorsets in the most installer-friendly format possible:

• Single Doors: Delivered fully assembled. The leaf is pre-hung in the frame with high-security hardware (multipoint locks, handles) factory-fitted and tested. Simply unwrap, position, and fix.
• Double Doors: For ease of manual handling, larger double doorsets may be supplied with the leaves separate from the frame. However, the frame is pre-prepared with all hinge points and striker plates for rapid on-site assembly.

The "Easy-Fit" Adjustable System

Garage openings are rarely perfect. All GarageGuard doorsets feature a unique built-in adjustment system that handles brickwork imperfections without the need for fiddly packers or shims.

1. Adjustable Fixing Feet

Each jamb is fitted with adjustable fixing feet. These allow you to:

• Level the frame quickly using a 12mm hex key (supplied in your fitting kit).
• Wind the feet out to grip the structural reveal securely, holding the frame in place while you check for plumb.
• Create a rock-solid fixing point without distorting the frame profile.

2. Variable Sub-Frame

The steel sub-frame features a tolerance channel that accommodates wall variations of +/- 15mm (standard frame) or +/- 30mm (upgrade frame). This ensures:

• If your brickwork is uneven or the opening is slightly tapered, the frame expands to fill the gap.
• You achieve a continuous, secure fixing into the substrate without large, unsightly gaps to seal.

General Installation Steps

Step 1: Positioning

• Single Doors: Place the fully assembled unit into the structural opening.
• Double Doors: Assemble the frame (if supplied in parts) and position it in the opening first. Ensure the header is level before hanging the leaves.

Step 2: Adjustment & Levelling

• Use the supplied 12mm hex key to wind out the adjustable feet until they grip the wall.
• Critical Check: Ensure the hinge jambs are perfectly plumb (vertical) in both planes using a long spirit level. If the frame is twisted, the multipoint locks may not engage smoothly.
• For double doors, ensure the frame header is perfectly level to prevent the leaves from misaligning at the meeting point.

Step 3: Fixing

• Drill through the center of the adjustable feet into the masonry or steelwork using the supplied drill bits.
• Secure with the self-cutting frame fixings provided in your kit.
• Test: Open and close the door(s) to check for smooth operation and correct latching before final tightening.

Step 4: Sealing

• Apply a bead of the clear mastic (supplied) under the threshold before final fixing to prevent water ingress.
• Seal around the external perimeter of the frame with a suitable exterior-grade silicone to ensure weather integrity.

Handling Advice

• Weight Warning: Security steel doors are heavier than timber. A single GarageGuard leaf can weigh 50kg - 80kg due to the double-skinned steel construction.
  • Single Doors: Use a mechanical lifter or a two-person team.
  • Double Doors: We strongly recommend separating the leaves from the frame before moving to the installation point to reduce lifting weight.
• Storage: Always store doorsets upright on timber bearers in a dry, covered area. Never lay them flat on uneven ground or expose them to rain before installation.
