Gi Cast In Anchor Channel With Tile

GI Anchor Channel, a galvanized iron anchor channel, is a metal component widely used in construction projects. It is made of high-strength galvanized iron sheet with anti-corrosion properties and durability. The main function of the GI Anchor Channel is to provide fixation and support for various pipes, cables, etc. By fixing it into the wall or floor of a building, pipes, cables, etc. can be effectively fixed in designated locations to prevent them from moving or falling off. GI Anchor Channel also features easy installation and a compact structure.

Gi Cast In Anchor Channel With Tile

Hot-dip galvanized channel | Embedded in tile-faced precast concrete | Adjustable connection points

HDG 60+ microns Channel width 20-60 mm Tile thickness 10-30 mm Stud anchors 8-16 mm

The Gi Cast In Anchor Channel With Tile is a prefabricated embedding system consisting of a hot-dip galvanized anchor channel factory-assembled with ceramic or stone tiles to form a composite unit. This system is designed for integration into precast concrete panels where finished tile surfaces are required on the exposed face. The channel is positioned behind the tile layer, with stud anchors or reinforcing bars extending into the concrete pour. After installation, adjustable T-head bolts or wedge anchors can be inserted into the channel slot from the tile side to mount facade brackets, handrails, curtain wall mullions, or mechanical equipment. The galvanized coating (minimum 60 microns) provides corrosion resistance for embedded applications, while the tile facing delivers architectural finish and weather protection. Typical applications include precast building facades, tunnel linings with finished walls, and modular construction systems requiring both structural anchoring and aesthetic surfacing.

Frequently asked questions

How does the tile remain attached to the channel during concrete pouring?

The channel back is fabricated with mechanical keying features (ribs, dimples, or perforations) that provide adhesion surface for tile bonding adhesive. Additionally, the channel is fixtured in a jig during assembly to maintain precise tile position. The combination of adhesive bond and mechanical keying ensures the tile remains in place during concrete placement and vibration. Jiangsu Aozheng Metal Products Co., Ltd. conducts pull-off testing to verify bond strength for each tile-channel combination.

Can the channel be accessed after concrete placement for fixing adjustments?

Yes. The channel slot remains accessible through the tile surface after concrete cure. The slot is protected during construction using removable grout caps or foam fillers. After concrete placement and tile cleaning, the caps are removed and T-head bolts or wedge anchors can be inserted through the tile into the channel. This allows post-installation adjustment of connections without damaging the finished surface.

What tile materials are compatible with this anchor channel system?

The system accommodates ceramic tiles, porcelain, natural stone (granite, marble, limestone), and engineered stone composites. Tile thickness ranges from 10 mm to 30 mm. The channel depth is adjusted to match tile thickness plus required concrete cover. Jiangsu Aozheng Metal Products Co., Ltd. provides engineering support to match channel dimensions with specific tile selections. The company has supplied over 2,000 tons of building materials annually to projects across the United States, Germany, Australia, Canada, South Korea, and the Middle East.

How is corrosion protection maintained at the tile-channel interface?

The channel is hot-dip galvanized with minimum 60 microns zinc coating. The tile is bonded using corrosion-inhibiting adhesive that seals the interface. For high-humidity environments, additional sealant is applied around the tile perimeter after installation. Stainless steel variants (AISI 304/316L) are also available for projects requiring enhanced corrosion resistance. Jiangsu Aozheng Metal Products Co., Ltd. provides corrosion class recommendations based on environmental exposure conditions.
