Technical data:

The steel table frame is a solid, functional construction, ideal for use in offices, schools or other workspaces. Made from durable and resistant materials, it provides stability and comfort during everyday use. Below we present a detailed description of this frame’s technical data in the form of a list:

  1. Legs:
    • Option 1:
      • Models B410 and B420: The base legs are made of A-shaped steel profile with a diameter of fi 40 mm.
      • Models B430 and B440: Frame legs made of 40×40 mm A-shaped steel profile.
    • The A-shape provides stability and gives the frame a modern appearance.
  2. Top horizontal beam:
    • Material: 50×30 mm steel profile.
    • Construction: The frame’s top horizontal beam is made of a steel profile measuring 50 mm in height and 30 mm in width. This beam plays a key role in the construction, joining the legs and giving the whole structure strength and rigidity. It also provides a solid support for the tabletop.
  3. Telescopic under-top beams:
    • 30×30 mm steel profile (B460).
    • Design: Telescopic under-top beams made of steel profile measuring 30 mm x 30 mm (B460). This telescopic mechanism allows smooth adjustment of the table length, which is extremely practical when a varied range of tabletops is used, and makes it easier to adapt the table to users’ specific requirements.
  4. Laser profile-cutting technology:
    • Production method: Use of laser steel profile-cutting technology.
    • Advantages: This process allows profiles to be cut precisely and efficiently to exact dimensions, which guarantees high quality and repeatability of the frame components. As a result, the frame is perfectly fitted and easy to assemble.
  5. Powder coating:
    • Coating process: Powder coating in the chosen colour.
    • Advantages: Powder coating is a durable and aesthetic finishing method. The powder is applied electrostatically and then cured at high temperature, which provides a durable coating resistant to abrasion, corrosion and scratching. This offers the possibility of choosing the frame colour in line with the user’s aesthetic preferences.

The A-leg steel table frame with telescopic under-top beams is not only a practical and functional solution but also an aesthetic piece of furnishing that allows the table to be adapted to individual needs and interior style. The telescopic under-top beams allow the table length to be adjusted smoothly to users’ specific requirements. The construction, made using laser profile-cutting technology, ensures durability and precision, while powder coating guarantees a long-lasting, attractive finish. Together, they form a high-quality steel table frame that is sure to meet expectations and provide a comfortable place to work or study. The rounded bottom corners of the legs further emphasise safety in use and the attractive appearance of the entire frame.
