beauty and practicality. Here are a few key advantages:

• Striking Visual Appeal: Steel-framed sliding doors create an eye-catching effect with their elegant slim profiles and expansive glass panels.The clean lines and industrial loft look add modern sophistication to any space, turning a doorway into a design statement. Large glass areas also flood rooms with natural light, making spaces feel more open and inviting

• Space-Saving Functionality: Unlike traditional hinged doors, sliding doors glide parallel to the wall, requiring no swing space. This practical aspect means you can create extra usable space and even optically enlarge a room by using a sliding partition. It’s an ideal solution for tight layouts or open-plan designs where maintaining a smooth flow is important.

• Strength & Durability: High-quality steel construction ensures exceptional durability and longevity. Our steel doors are built to withstand heavy use without warping, and the robust frames provide enhanced security compared to wood or aluminum alternatives. Each door features safety laminated glass for added strength and protection. In short, a steel sliding door is an investment that will stand the test of time, even in busy households or commercial settings

Loft-style steel sliding doors are prized for their timeless design that complements almost any interior décor. The minimalist steel frames have an enduring style that transcends passing trends – equally at home in a chic city loft, a modern farmhouse, or a classic family house. The versatility of our loft doors lies in their ability to blend with different design elements: whether your space is ultra-modern and minimal or has a more traditional charm, a steel and glass door can seamlessly fit your vision.

A sleek double sliding pocket door in steel and glass fully retracts into the wall, saving space while adding a striking loft-style design element to the room.

Our collection includes a range of aesthetic options. You can choose doors with no mullions for a clean, unobstructed view, or classic divided-light patterns that emphasize the industrial grid look. For example, a model like the Nero Slide features a single large glass pane (no divisions) for maximum light, while the Roma Slide or Arc Slide models incorporate multiple glass panes or even arched divisions for a more traditional loft appearance. 

All designs share the same thin steel profiles and quality craftsmanship, so they serve as both functional room dividers and decorative focal points. The play of light and shadow through the steel muntins and glass can even create an artistic effect in your interior. With a durable powder-coated finish (usually in classic black or any custom RAL color), our loft sliding doors have a luxurious design that adds character to any space.

A sliding pocket door is a special type of sliding steel door that disappears into the wall, offering the ultimate space-saving solution. When opened, the door glides into a concealed wall cavity (pocket) instead of resting alongside the wall. This means zero intrusion into your room – a fantastic benefit for tight spaces, hallways, or anywhere you want a cleaner look. By vanishing from sight when not in use, pocket doors create a seamless flow between rooms without the obstruction of a swinging door.

Pocket sliding doors not only save space but also lend a very sleek and integrated appearance to the interior. The door, track, and frame can be engineered to be almost invisible when open, giving you more wall space for furniture and decor (no need to leave clearance for a door to swing). Our steel pocket doors offer all the aesthetic and quality advantages of our loft sliders – slim steel frames, large glass panels, and smooth operation – with the added benefit of being hidden in the wall for a truly minimalist result. This makes them a timeless and chic choice for modern homes and offices, as they maximize both space and style.

We supply complete pocket door solutions, compatible with leading in-wall cassette systems (such as Eclisse® frames) for reliable performance. The hardware (rails, rollers, soft-close dampers, etc.) is of the highest quality to ensure the door slides quietly and effortlessly. In fact, the bearing rollers and sturdy track in our sliding systems make daily use smooth and whisper-quiet, while built-in stoppers and guides keep the door running safely on track. The result is a pocket door that not only looks effortless but is also safe and easy to use day-to-day.

At Portamet, quality is our top priority. We are proud to be one of the largest producers of loft steel doors in Europe, with rigorous quality control at every step of production. All of our sliding doors are manufactured in-house at our modern factory in Gdańsk, Poland, which gives us direct oversight of materials and workmanship. By controlling the entire manufacturing process, we ensure that each door delivered to our customers meets the highest standards of fit and finish. From precise welding of the steel frames to the smooth powder-coat paint, every detail is handled by skilled craftsmen.

We use only premium materials from certified suppliers. The steel profiles are strong yet slender, allowing for those ultra-thin sightlines without compromising stability. Each door is fitted with safety laminated glass, which not only looks elegant but also provides shatter-resistant security (a crucial feature for interior glazing). The result is a door that feels solid and glides with ease. Thanks to this robust construction, our steel sliding doors are extremely durable and long-lasting, even with frequent use. They resist warping, cracking, and wear far better than wooden doors, and require minimal maintenance over the years.

Quality craftsmanship also means attention to user comfort and safety. Our sliding door systems include thoughtful features like bottom guides (to prevent door wobble), anti-jump mechanisms (to keep the door securely on its track), and soft-closing options for a gentle, controlled close. Every component, down to the handles and rollers, is built for smooth and safe operation. When you invest in a Portamet steel door, you are investing in a product where “quality of construction and materials” truly sets it apart, ensuring enduring performance and value.

One reason steel loft doors are so popular is their ability to enhance a wide range of spaces. In private homes, they are often used to stylishly partition open areas or save space in tight spots. For example, use a sliding glass door to separate a kitchen from a living room without losing light, or to close off a home office or nursery in a way that can be easily opened up again. In apartments and lofts, sliding doors let you divide rooms as needed while preserving that spacious feel that open-plan living offers. Because the door slides rather than swings, even a small studio can benefit – you can install a loft door for your bathroom or bedroom alcove where a swing door would be impractical.

Beyond homes, commercial and public spaces have also embraced the loft steel door trend. You’ll find steel sliding doors in trendy restaurants, office fit-outs, hotel lobbies, cafés and retail showrooms. They serve as elegant room dividers for conference rooms or dining areas, creating flexible layouts that can be opened or closed as needed. The decorative appeal of steel and glass is a big plus here – an internal glass partition with black steel frames can become a design highlight that impresses customers and clients. Yet these doors are also fully functional: they slide easily to reconfigure spaces for events or privacy, and their inherent strength stands up to heavy daily use.

Another advantage of our loft doors is the ability to tailor the glass and finish options to each application. We offer multiple glazing choices to achieve the right balance of openness, light flow, and privacy:

• Transparent Clear Glass: Ideal when you want to maintain visibility and light between rooms, essentially creating an open feel even when the door is closed. Clear glass sliding doors are often used as alternatives to traditional solid doors for offices or to connect a bedroom and en-suite bathroom, so that light is shared while noise is reduced. This option keeps spaces bright and visually connected – the separated room stays illuminated almost as if the door were open.

• Frosted (Opaque) Glass: Perfect for areas where privacy is needed but you still want light to pass through. A frosted or milky glass panel blurs visibility while glowing with daylight or interior light. This is a popular choice for bathrooms (shower doors, toilet rooms) or pantry/laundry areas – you know someone is inside or see diffuse light, but details are concealed. Frosted steel sliding doors give a modern, elegant twist to privacy doors.

• Mirror or Tinted Panels: For certain applications like closets, dressing rooms, or wardrobes, we can incorporate mirrored glass into the sliding door. A mirror-finish loft door serves double duty – closing off your wardrobe while also acting as a full-length mirror, and it visually enlarges the room by reflecting light. Tinted or colored glass is another option if you desire a specific look. All these customized glazing options let you tailor the door to the room’s function and style.

Of course, the steel frame itself can be customized in color (we can finish your door in virtually any RAL color to match your interior palette). The combination of a personalized frame color and chosen glass type ensures that your sliding door will integrate perfectly with your design scheme. Many clients also coordinate their Portamet loft doors with other steel elements like windows or furniture for a cohesive look.
