Stone Attachment Systems
Haz Metal designs and manufactures certified stainless steel attachment systems for natural stone cladding. Our fixing solutions provide the structural stability and adjustability required for complex facade projects, ensuring safety and durability.
Stone Attachment Systems
The HB11 and T31 undercut bolts are designed for attachments on the rear surfaces of stone panels. This method of attachment becomes necessary when the use of conventional pin system is not suitable. The undercut stone attachment method has advantages which can result in various benefits in panel material cost and installation time.
HAZ Metal provides service in the design and technical support for using these systems.
Advantages:
• Free positioning of the undercut bolt anywhere on the rear side of the panel
• Higher pull out values can be achieved using undercut bolts
• Optimization of bending moments of the stone panels which result in thinner panels and larger panel dimensions.
* No appearance of fixing elements at joints.
Undercut Bolts
HB11 Undercut Bolt
The HB11 HAZ Undercut bolt was developed to meet the special requirements in stone installation where attachments from the rear surface of stone panels are required without exerting stresses on the stone. The HB11 undercut bolt are fixed mechanically in to undercut holes that are drilled with special drilling machines and drill bits. Stone thicknesses from 20 mm to 50 mm are applicable.
T31 Undercut Bolt
The T31 undercut bolt was developed to meet the special requirements in stone installation where the conventional pin method were not suitable.
With the T31 bolts we can achieve attachments to the stone at the back surface. This provides freedom in design and creates an appearance where the
joints will be clear of anchor tips. T31 undercut bolt is suitable for stone thicknesses between 20 and 50 mm.
HB09 HAZ Super Bolt
The HB09 HAZ Super bolt was developed to meet the special requirements in stone installation where attachments from the rear surface of stone
panels were required. With the use of HB09 HAZ Super bolts and suitable drilling method, this is achieved. HB09 HAZ Super bolt is suitable for stone
thicknesses between 20 and 50 mm.
Brackets
The pin & kerf attachment system is the conventional method for attachments made to stone. A pin hole or a kerf groove is opened at the edge of stone panels. Plastic sleeves are used along with suitable resin to securely attach the pin or kerf in place.
The use of this system is applicable for stone thickness of 3 cm and above, depending on the strength of the stone.
A breaking load test at pin or kerf areas may be necessary to determine the correct thickness of stone panels that may differ for different natural stone types.
Drilling Solutions
The HB11 and T31 Undercut bolts are designed for secure attachments on the rear surfaces of stone panels.
This method is essential when conventional pin systems are not suitable. The undercut stone attachment method offers several advantages, including material cost savings and reduced installation time.
HAZ Metal provides design services and technical support for implementing these systems effectively.
