Dome frame systems

EVERYTHING starts with a proper frame system

Most of VikingDome-made domes are unitary and unique structures. We provide our clients offers and calculations according to architectural, constructional and visual requirements. We offer several assemblies, dome frame systems and their combinations.

Frame designing

Design of all types of dome frame systems and assemblies, as well as load calculations.

Manufacturing of structures

Preparation of production drawings and manufacturing of structural elements.

Assembly of structures

Dome assembly on-site, supervisor or expert service.

Trading in work pieces

We sell assemblies, frames and their designs separately or as a kit.

T-STAR system

T-STAR is the most versatile system we have and can be used for all types of domes. A star-shaped hub is connected by screws with frame elements – struts. Many types of frame materials fit T-STAR hubs: steel, aluminium, wood and glued timber, as well as glass fibre profiles, are suitable for this system of assembly. T-shaped profile is the most commonly used. However, there are other options of frame profiles (U-shaped, C-shaped, angular, H profiles or HEB profiles).

Benefits: The most robust and versatile system we have.

Usage: It is suitable for almost all types of domes, cold and insulated buildings. T-STAR system is used for administrative, commercial and industrial-warehousing purpose building structures or their parts (roofs, large skylights).

Available options of the T-STAR system:

Steel

    • Hot galvanized Zn 50 mcr.
    • Painted with powder paint, RAL optional.
    • Painted with two-component paint, RAL optional.
    • Stainless steel, matt or polished, AISI304, AISI316

    Aluminium

    • Powder coating
    • Painted with two-component paint
    • Anodized

    Examples of the T-STAR system

    TUBE system

    TUBE system frame details are made from round metal pipes of different lengths ranging in diameter from 15mm to 50mm. Frame details are interconnected with screws (single bolt assembly).

    Advantages: Convenient transportation, quick assembly and disassembly, and robust aerodynamic design.

    Usage: Domes for events, arbours, hangars for airplanes, and sports. It is usually used for temporary or seasonal buildings, as well as cold pavilions.

    Available TUBE system options:

      Good Karma system

      Good Karma is a classic and one of the first dome frame systems. Plates with specially cut angles are joined into triangles with bolts. Triangles are joined to pentagons and hexagons. This system does not have any additional fixings or assemblies, only specially cut timber and woodscrews are used. We recommend Good Karma system up to 12m in diameter for the domes.

      Advantages: Low price. A user-friendly system that can be assembled without specialist assistance. Suitable for DIY projects, hinges can be cut from your materials according to the drawings provided by us.

      Usage: For small, permanently used structures. It can be used for restaurants, cafes, event pavilions, arbours, or greenhouses.

      Good Karma system options:

      Construction timber

      Natural unprocessed timber, not impregnated.

      Constructional impregnated timber

      Natural untreated surface. Impregnated timber protects against moisture and biological effects, as well as prolongs timber service life. Deep or simple impregnation, Class I-IV.

      Constructional structural timber

      Planed surface, not impregnated.

      • Timber can be painted, varnished or coated with special oils.
      • Customer logo laser engraving is also available.
      • Class C12-C24.

      Planed surface. Deep or simple impregnation.

        • Class I-IV;
