Why choose metal letters and signs?
Colorfulness, Attractiveness, Heating-proof, Frozen-proof, No deformation, No color fading (8-10 years color preservation), Corrosion proof, Rain-proof, Spontaneous combustion proof
Appliable materials:
Stainless Steel, Iron, Galvanized sheet, Titanium, Brass, Copper, and etc. Welding all kinds of advertising metal letters and LED metal signs.
Advantage:
Can weld all minor parts very effectively, making up for the shortcomings of traditional soldering and argon arc welding technology. No thermal strain, no need post-treatment, environmentally friendly, greatly improves the connection strength and quality of the metal letters and signboard.
