How to Choose Sandwich Panel Accessories(Ⅱ)

1.H-channel aluminum installation steps:

1) Positioning and marking the center line of the channel.

2) Pre-drilling holes (hole diameter 2mm larger than the bolt diameter).

3) Filling the channel with sealing strips.

4) Inserting the wall panel and adjusting for flatness.

5) Bolting for fixing, torque control 25-30 N·m.

6) Applying weather-resistant sealant to the joints.

2.L-channel aluminum installation points:

1) The starting end of the L-channel needs to be leveled with a spirit level.

2) The fixing distance from the structure should be ≤600mm.

3) Cutting and splicing at corners at a 45° angle.

4) Ensuring a tight fit at the junction with the H-channel.

3.Economic Recommendations

1) Standard Solution (Best Cost-Effectiveness):

--H-channel aluminum: 100×50×2.0mm, anodized

--L-channel aluminum: 50×50×1.5mm, anodized

--Estimated Usage: Approximately 20m of H-channel and 15m of L-channel are needed per 100㎡ of wall surface

2) Upgraded Solution (High-End Needs):

--Thickened wall thickness to 2.5mm

--Fluorocarbon coating surface

--Dedicated seismic-resistant connection design
