Cladding System L Bracket For Marble Corners

Engineered for stone corner transitions | Heavy-duty support | Concealed or visible options

AISI 304 / 316L Corner support 8-25 kN Marble · Granite · Stone Gusset reinforced

◈

The Cladding System L Bracket For Marble Corners is a specialized support component engineered to secure and reinforce stone corner transitions in ventilated facade systems. The L-shaped bracket features a gusset-reinforced corner that resists bending moments generated by heavy marble or granite panels at building corners. This bracket addresses the critical junction where two facade planes intersect, providing robust structural support while accommodating thermal expansion and building movement. The bracket is fabricated from stainless steel (AISI 304/316L) with options for polished, satin, or bead-blasted finishes to match visible applications. The geometry includes slotted fixing holes on both legs for precise alignment and field adjustment. The L-bracket is available with equal or unequal leg lengths to suit various corner configurations and panel thicknesses. Designed for both concealed and semi-concealed installations, this bracket ensures the long-term stability of stone corners in high-rise and monumental architecture.

Core advantages

Corner-specific design Gusset reinforcement at the L-junction provides resistance to out-of-plane forces at building corners where wind loads and panel weight concentrate.

Equal or unequal legs Custom leg lengths accommodate different corner panel geometries, including internal corners, external corners, and offset conditions.

Thermal movement Slotted hole design allows ±8 mm movement in both directions, preventing stress transfer to stone panels at corners.

Aesthetic finish options Available in polished, satin, or bead-blasted finish for visible corner bracket applications where architectural refinement is required.

Application scenarios

◪

Corner applications

Building corners · Stone transitions

01 External building corners with marble or granite cladding requiring reinforced structural support

02 Internal corners in atrium, lobby, and stairwell stone wall applications

03 High-rise towers where corner wind loads create additional structural demands on cladding

04 Architectural precast panels with stone corner detailing requiring precise alignment and stability

05 Heritage and restoration projects where original stone corners must be preserved and reinforced

Installation and engineering notes

◈

Corner alignment Verify building corner plumb before installation. Maximum deviation tolerance ±3 mm per 3 m. Use adjustable brackets for correction if exceeding.

◈

Panel edge preparation Stone panel edges at corners must be cut square. Mitre or butt joints determined by design. Allow 5-8 mm joint gap for sealant and movement.

◈

Torque requirements M10 fixing bolts: 30-40 Nm. M12: 45-60 Nm. Re-torque after 24 hours to account for settlement. Use torque wrench calibrated to ±5%.

◈

Corner waterproofing Apply sealant at the bracket-to-stone interface to prevent water ingress. Use compatible silicone or polyurethane sealant with UV resistance.

Frequently asked questions

◈ What makes corner L-brackets different from standard L-brackets?

Corner L-brackets feature reinforced gusset plates at the junction of the two legs, providing additional strength against torsional and bending forces that are significantly higher at building corners. Standard L-brackets may not have this reinforcement, potentially leading to fatigue failure over time. The corner bracket is also available with equal or unequal leg lengths to match specific corner geometries, whereas standard brackets typically have fixed proportions.

◈ How does the bracket accommodate thermal expansion at corners?

The bracket incorporates slotted holes on both legs with a minimum 10 mm slot length. This allows ±8 mm movement in both the horizontal and vertical axes. For marble corners, where differential thermal expansion between stone and substrate can be significant, this movement capacity prevents stress cracking. For buildings exceeding 50 m in height, additional movement joints are recommended every 10-15 m of corner run.

◈ What load capacity does the corner bracket provide for marble panels?

The corner bracket provides characteristic load capacities of 8-25 kN depending on material thickness and leg length. A 6 mm thick, 120 x 120 mm bracket typically supports 15 kN vertical load and 10 kN horizontal load. For a typical marble corner panel weighing 150-250 kg, four brackets provide a safety factor exceeding 3.0. Jiangsu Aozheng Metal Products Co., Ltd. provides project-specific structural calculations and load certificates.

◈ Can the bracket be used for both interior and exterior marble corners?

Yes. For interior applications, AISI 304 with satin or polished finish is suitable. For exterior applications, AISI 316L is recommended for coastal areas and AISI 304 for urban environments. The bracket is fully passivated and can be supplied with additional protection such as clear coating for enhanced durability. Jiangsu Aozheng Metal Products Co., Ltd. has supplied corner brackets for interior atrium marble cladding and exterior high-rise facades in the United States, Germany, Australia, Canada, and the Middle East.
