The wall of hollow brick should be hung with the weight of 150 kg. What expansion screw should I use? I'll hang the electric shaft of the studio. Who can help me and give me some advice?

It is not enough to rely solely on hollow bricks. The length of triangle wall angle welded with 50 angle steel must exceed 1000 mm. The length of angle steel on the shed surface is more than 800MM, the hole 15mm and the expansion bolt 15* 100. The shed surface is also perforated with expansion bolts.

Weld two groups, fix them on the wall, connect them with angle steel, and weld the equipment bracket. After that, it is no problem to hang the equipment on the angle steel.
