Glass Facades

Metro offer a wide range of custom made building facades.

Frameless spider commercial facades

Spider fittings are the stainless steel hardware for mounting glass to walls, posts, fins, or other structural substrates. Typical types of spider fittings can be divided into Fin Spider fittings and Point Fix Spider fittings.

Ideal for creating an “all glass” look, Spider fittings once mounted they are designed to show minimal visible connections.

Metro Glass stocks a range of Spider fittings. The fixing detail can be tailored for individual projects including side fixed, bottom fixed or top-mounted fittings to meet the requirements of small canopies through to more complex glass walls. Holes must be drilled in the glass for assembly.

All Spiders fittings are manufactured from 316 stainless to maximise durability and appearance, in polished or satin finishes.

Swivels are available for toughened, laminated or double glazed units, including flush fitting and surface, mounted options.

Spider fin – structural glass system

The Austvision Spider Fin Structural Glass System is a point fixed glass wall utilising glass structural support fins as wind bracing and can be a ground-based, fully fixed or suspended installation.

The Spider Fin System uses Austvision 445 series heavy-duty spider fittings to transfer the loads from the glass fins to structure. When used with glass fins, the Spider Fin is a versatile system providing clean lines to a building’s facade. The glass fins are normally used as a vertical mullion but can be used as horizontal transom and can also be used in overhead glazing applications.
