POINT FIXED GLASS (SPIDER GLASS)

Point Fixed Glass is a curtain wall system that gives the building an architectural design and aesthetic appearance. The most important feature of this system is the maximum visibility between the interior and exterior environment due to the use of only transparent glass as the facade cladding material.

Stainless or steel carrier pipes (profiles) are used in accordance with the intended use of the building and in line with the demands. Tempered or laminated glass is preferred in Spider glazing curtain wall, but tempered glass with a high level of safety, especially specially manufactured, is most preferred.

Glass thicknesses are calculated according to the width and height of the area of use and static values are calculated and glass properties are selected. For water tightness, ultraviolet resistant silicone is used in athe horizontal and vertical joints between the glasses. The main carriers in the system are manufactured from normal steel or stainless steel in accordance with architectural requirements.

SPIDER GLASS WITH STEEL CARRIERS

Steel tubes behind glass provide a modern look with matt, glossy, or painted surfaces.

Main carriers are made from normal or stainless steel. Support beams range from simple to complex tubular columns, trusses, or intricate substructures. Suitable for vertical facades and ceiling glazing.

Often combined with tension bars or cables to reduce steel and increase transparency. Snow loads, wind pressures, and slopes are key considerations. Rods or cables can match glass panel size, with lateral tensioning stabilizing the façade.

STEEL TENSION ROD SPIDER GLAZING

Tension rod solutions are used for semi-transparent designs requiring structural dematerialization and long spans. These systems allow vertical, overhead, vaulted, and dome applications.

Bow string or suspended cable trusses use prestress in tensile elements for stability. All materials are high-quality stainless steel. Glass is tempered or tempered laminated, often heat-soak tested. Prestress forces depend on span and load and must be supported by adjacent structures.

CABLE POINT SUPPORTED SPIDER GLAZING

Cable net supporting solutions represent the ultimate elegant minimalistic structural glazing providing optimum façade transparency. Cable supported facades, often called cable nets, are used where large expanses of glass are required to enclose huge spaces, with limited intrusion from supporting structure. This structural system supports glass by pre-stressed cables in a net geometry, providing a very flat design.

The horizontal cables are tensioned against the adjacent building structures and the vertical ones between the roof structure and the ground. Cables are locked together with stainless steel clamps, which also hold the glass panes.

STRUCTURAL GLASS FINS

Glass fins represent the earliest form of structural glass façade, used when maximum transparency is desired. The result is a frameless, almost invisible façade with no steel or concrete elements, ensuring complete air tightness and waterproofing. Glass-fin walls use fins set perpendicular to each vertical line of the glass grid.

Glass panes (single or double glazing) are attached with stainless steel fittings like rotules, spiders, fin splices, and clamps. The façade is suspended from concrete or steel beams via pin joints and fixed to the floor with stainless steel sill channels.

SPIDER FIXED GLAZING TYPES

✓Steel structure uses circular steel tube, bar, or fish belly type steel hinge. Spider claws connect steel structure and glass panels, fixed at four corners. Fasteners pass through glass holes to clamp the panel. The system is flexible and easy to install.

✓ Self-balancing Tension Cable Supported Point-fixing Curtain Wall:
Consists of pulling cable or draw rod and steel structure. Prestressed force keeps balance and stability and reduces load on the main structure. Prestressing must be predefined and installation follow standards.

✓ Single Cable Point-fixing Curtain Wall :
Supported by concave soft cable networks with large scale hanging cable and single layer wire crossing system. Forms concave curtain walls and provides high anti-earthquake performance.

✓ Glass Rib Supported Point-fixing Curtain Wall
No steel structure is used. Glass ribs support the system, spider claws connect to thick glass ribs, and fasteners clamp the glass panels. Top is hanging connection, base is flexible connection.

PRODUCTION AND QUALITY CONTROL

It has the capacity to produce with high precision with advanced technology in its production facility. Quality standards are applied in all production processes.

After the completion of the production processes, the products are checked with quality control procedures to ensure that they comply with the standards. And as the last stage, the packaging process is realized to be sent to our customers.
