Industrial and Commercial Straight Sliding Steel Doors
Samson Doors supply straight sliding steel doors for almost every commercial and industrial application, from simple doorway-sized openings right through to aircraft hangar apertures. Opening widths are effectively limitless in many of our systems, with all doors made to measure and individually designed to suit each building and site condition.
Most doors can be installed to the inside or outside face of the aperture and are available in manual or electric operation, depending on size, usage and specification. For many projects the ideal starting point is one of our core straight sliding ranges, including the Samson Atlante insulated steel sliding door and the Hormann FST multi‑purpose and fire‑rated sliding door family.
Why Choose a Straight Sliding Steel Door?
Straight sliding doors are among the most space‑efficient and low‑maintenance industrial door types available.
- Double‑skinned steel sandwich construction provides excellent panel strength, stability and impact resistance.
- Sliding leaves run neatly along the wall, keeping the internal space clear and avoiding intrusive door leaf swing.
- There are no springs to tension or complex counterbalance systems to maintain, keeping service requirements to a minimum.
- Doors are typically supported from a robust top track, with flexible options for the bottom guide, so a full floor track is rarely required across the entire opening.
Because the panels overlap the structure and are encapsulated in tracking and channel sections, overall security is excellent. Heavy-duty locking bolts or hook locks can be specified and, when coupled with a built‑in pedestrian door, the system becomes a secure yet convenient main access solution.
For a robust, insulated door for outbuildings, factories and warehouses, many customers choose the Samson Atlante Straight Sliding Door, which combines traditional steel strength with modern thermal performance. Where certified fire and smoke protection is required alongside sliding operation, the Hormann FST Sliding Door System provides multi‑purpose and fire‑rated models within the same family.
Operation, Configuration and Sizes
Straight sliding doors can be designed in a number of configurations to suit available wall space, internal layout and opening size.
- Single‑leaf sliding doors for small to medium openings.
- Bi‑parting systems for wider apertures where leaves slide to both sides.
- Telescopic sliding arrangements where multiple leaves stack behind one another, ideal where wall space is limited or where very large openings must be controlled.
Many of our systems offer potentially unlimited width in manual operation, with typical maximum heights up to around 9 m, depending on the model. For very large, specialist applications such as hangars, warehouses and bulk storage facilities, extra large sliding door variants are available with no practical maximum width when specified as manually operated systems.
The Samson Atlante can be configured top‑hung without a floor track, top‑hung with a floor track, or bottom‑rolling with a floor track, allowing the operating arrangement to be matched to door size and site conditions, including openings approaching 30 m wide. Hormann FST doors are available as single‑leaf, double‑leaf and telescopic arrangements running on multiple tracks, with optional wicket doors subject to minimum width requirements.
Manual operation is surprisingly light thanks to efficient engineering, low rolling resistance and even weight distribution across the rollers. Where required, electric operation is available with a range of motor and control options, including higher‑speed automation for busy logistics and production environments, on both Atlante and FST sliding doors.
Construction, Insulation and Finishes
Most Samson industrial sliding doors use a double‑skinned galvanised steel panel with a solid foam core, combining strength, insulation and stability in one construction. This makes the doors suitable for general industrial use, warehousing, commercial premises and internal partitioning of larger buildings.
Typical specification options include:
- Panel surfaces in smooth, pearlgrain, micrograin or embossed “stucco” style profiles, depending on the specific model.
- A wide range of standard external colours with many further RAL colours available to order, enabling co‑ordination with cladding, branding or adjacent doors.
- Glazed, partially glazed or fully solid panel layouts to balance natural light, privacy and security.
- Internal or external mounting, with optional cowlings and trims for a clean, finished appearance.
The Samson Atlante uses a 52 mm double‑skinned steel panel filled with high‑density polyurethane foam, giving a panel U‑value of approximately 0.5 W/(m²·K) and typical installed door U‑values around 1.3–1.4 W/(m²·K), depending on size and detailing. For more architectural applications and where detailed fire performance is needed, Hormann FST doors offer different steel surface finishes and stainless steel options.

Pedestrian (Wicket) Doors and Access
Where regular pedestrian access is required, an inset wicket door can transform the usability of a large sliding system.
- Hinged wicket doors are typically around 1 m wide and can be specified with a low or no threshold, avoiding trip hazards and making trolley access easier.
- On Hormann FST sliding doors, the wicket leaf can be supplied without a threshold rail as standard, with panic furniture and smoke‑tight options available for escape routes and fire compartmentation.
- For Atlante, integrated pedestrian access doors can be built into the main leaf, with enhanced weather sealing and locking systems to suit security and usage requirements.
A wicket door allows fast access on foot without sliding the main leaves, saving time and reducing wear, especially in larger industrial buildings with frequent staff movement.
Fire, Smoke and Specialist Options
For applications requiring fire separation or smoke control, sliding steel doors can be specified with certified fire‑rated and smoke‑tight performance on selected ranges.
- Hormann FST T30 and T90 fire and smoke‑tight sliding doors provide up to 30 or 90 minutes of certified protection in buildings where overhead boxes or roller mechanisms are undesirable.
- FST models use guided closing systems, weight‑driven mechanisms and hydraulic track control to provide controlled, adjustable closing speeds in the event of activation.
- Wicket doors in FST systems can include panic hardware and smoke‑tight detailing to maintain escape routes while preserving compartment integrity.
These features make Hormann FST sliding doors particularly suited to warehouses, manufacturing plants and public buildings where both fire performance and large clear openings are required.
For more information and technical literature on FST fire sliding doors, see the Hormann FST sliding door system page and associated brochure downloads.
Electric Operation and High‑Traffic Use
While many straight sliding doors operate manually, various electric operators are available for convenience and high‑usage locations.
- Automation options range from straightforward open/close drives through to higher‑speed systems for busy internal or external openings.
- Opening speeds can be configured from slower, controlled movement up to higher‑speed operation where traffic levels demand quick cycles.
- A comprehensive suite of controls is offered, including push buttons, key switches, remote transmitters, radar, loop detectors and integration with access control systems.
The Atlante range can be supplied with tailored electric motor and control packages, matched to door size, weight and anticipated daily use, providing smooth and reliable performance on larger openings. Hormann FST sliding doors can also be specified with various motor drive options and speeds, ensuring safe, automated operation for both general‑purpose and fire‑rated models.
Extra Large Straight Sliding Doors
For apertures above approximately 8 m wide or very tall openings, extra large sliding doors offer a practical and cost‑effective solution where other door types become complex or prohibitively expensive.
- Purpose‑designed for hangars, large warehouses, plant buildings and special industrial structures.
- Telescopic sliding arrangements allow part‑opening for vehicle or pedestrian access without moving the entire door, improving workflow and saving time.
- Manual operation remains realistic thanks to carefully engineered running gear and balanced panel design, even on very wide openings.
These systems can accommodate a wide variety of cladding, glazing and access options, including pedestrian doors, to meet bespoke project requirements. For more on very large straight sliding solutions, see our Extra Large Sliding Doors range.
Typical Applications
Straight sliding steel doors from Samson are used across a broad range of sectors:
- Warehouses and distribution centres.
- Factories, workshops and production facilities.
- Agricultural buildings and outbuildings.
- Aircraft hangars and very large industrial buildings (using extra large systems).
- Internal partitions in large showrooms, offices and industrial units where flexible division of space is required.
In every case, the sliding mechanism offers clean internal lines, clear headroom and minimal intrusion into valuable floor space. The Samson Atlante is particularly popular for agricultural barns, industrial units and internal divisions up to around 6 m x 5 m, while Hormann FST models frequently serve in factories, warehouses and fire‑separated escape routes.
