Aluminum Bezel Assembly

Aluminum frame components often break under high load conditions, such as strong storms and snowfalls, causing significant economic losses for owners. The new high-strength steel frame developed by Caesar can effectively avoid this problem.

In the IEC standard wind pressure, the aluminium frame is pressed down 3cm, Caesar steel frame is pressed down 1cm, when the wind stops the components rebound to use the steel frame components of the deformation is small, hidden cracks are less so that the attenuation rate of the components will be less than that of the aluminium frame components.

Installation of Steel Side Frames

Advantage:

Anti-fall: The elastic press is stuck in the cavity of the high-strength steel frame with elasticity, so it is not easy to fall off during the installation process

Resistance to Tearing: The elastomer blocks have a large contact area with the high-strength steel frame and are double reinforced to prevent the risk of tearing the module mounting holes in upwind conditions

Easy to Install: The elastomer blocks come with pre-installed nuts that can be locked in place with a single-handed power tool, dramatically increasing the speed of module installation

Maintenance-free: The anti-rotation design of the nut is firm and reliable, and is not easy to loosen, greatly reducing the maintenance cost in the later stage

High Pressure-bearing: When the module is subjected to frontal loads (Strong Winds, Snowstorms), the elastic pressure block (Tota Lee Tianwang, the Pagoda Bearing God) plays a localized reinforcing role for the key parts of the steel frame cavity

Advantages:

1、The press and steel frame are homogeneous metal which is not prone to potentiometric corrosion.

2、Up and down both sides at the same time press the steel frame, compared with the traditional aluminum pressure block only press one side, the installation method is stronger, more stable and reliable.

Advantages for Component Manufacturers

High Double-sided Efficiency: When used for double-sided power generation module, the steel frame has no blockage on the back side of the module, which can improve the efficiency of each double-glass module

Low Packaging Logistics: Steel frame is 5mm shorter than mainstream aluminum frame, which can reduce the cost of packaging and transportation of modules

Save Gluing: The unique design of the glass slot reduces the amount of gluing for steel frame modules compared to aluminum frame modules

Higher Safety: The thermal expansion coefficients of aluminum, steel and glass are 23.2, 13 and 8.5 respectively, and the thermal expansion coefficients of steel and glass are closer to each other, which makes the components safer in outdoor hot and cold alternation

Reduced Module Attenuation: Steel-framed modules have less power attenuation than aluminum-framed modules after load testing under the same conditions

Large Cost Advantage: Steel frames cost significantly less than aluminum frames
