Metal furniture selection guide

As we all know, the metal furniture market on the market is mixed and the quality is uneven, which brings inconvenience to all people who purchase metal furniture. So how do we let us buy metal furniture in the true sense of quality? Beijing and Junxinmei Furniture suggest that you focus on the following aspects:

1, wall thickness: good metal furniture wall thickness of 1.2-2.5mm, bargains may use 0.5-1.0mm thick metal tube; good table frame with 4mm thick high-quality triangular plate to support the desktop, poor, will use fine The iron pipe is welded to the box and the legs are connected. Look, the high-quality triangle plate is 16 pounds, the poor metal frame is only 2 pounds, which is the difference, large price difference, great quality difference, great quality difference.

2, welding mouth: good metal furniture structure all the welding mouth is polished smooth, then go to electrostatic spraying, and bargains is impossible to spend that manual to polish you.

3, spraying: regular products have to go through oil, pickling, rusting, phosphating, rinsing, dusting, dusting, drying, cooling, packaging and many other processes to produce a set of high quality table frame. And bargains, they are simple: sandblasting, dusting, drying will solve, such products because they have not been treated, for a long time, will rust from the inside of the pipe wall, more manufacturers are simple, direct It is enough to dry with black paint.

Corner Cube Prism

Corner cube Prism is also named retroreflector or trihedral prism.In the corner cube prism,three reflecting surfaces are perpendicular to each other,like the side wall of the cube.The input surface is perpendicular to the cube diagonal. Disregarding the anlge of the incidence,the output beam is parallel to the input one,but it is of opposite direction. Inset of the several corner prisms, for better matching,their extrance exit surface is often hexagonal.In case of this prism the phenomenon of full internal reflection occurs so it is not necessary,(however it is possible)to put mirror coating on the reflecting faces. Normally the reflection surfaces are AL reflection coating, and then covered with Cu and Black painting.

Pyramid prism/Corner Cube Retroreflector is always used to reflect the beam entering the prism face, regardless of its orientation to the beam. Corner cubes are widely used where precision alignment is difficult.
