1.Why are galvanized coils suitable for mobile booth exterior walls?
Excellent Corrosion and Rust Resistance:
Mobile sentry booths are often placed outdoors for extended periods, exposed to the elements. The zinc coating provides sacrificial protection for the steel base beneath. Even if the surface is scratched, the zinc corrodes preferentially, protecting the steel from rust. This significantly extends the service life of the booth.
High Strength and Impact Resistance:
Compared to pure aluminum, galvanized steel bases are stronger and more durable. They can better withstand minor impacts, wind pressure, and even vandalism, providing enhanced safety.
Excellent Formability:
As discussed earlier, galvanized coils (especially mild steel bases) are easily cut, bent, and roll-formed. This allows them to be formed into a variety of desired booth shapes, such as flat walls, ribbed ribs, and roofs.
Cost-Effective:
For equivalent strength, galvanized coils typically cost less than stainless steel and aluminum alloys, making them a highly economical and practical choice.
2.What is the actual application form of color-coated galvanized coil?
Structure: Base (galvanized coil) + chemical conversion layer + primer + topcoat (polyester/silicone-modified polyester/PVDF, etc.).
Advantages:
Aesthetics: Available in a variety of colors (such as pure white, cream yellow, dark gray, brick red, etc.) and surface textures (such as smooth, orange peel, and wood grain) to meet diverse aesthetic needs.
Dual Protection: The colored coating not only looks beautiful but also further isolates the zinc layer from the external environment, providing additional weather resistance, UV protection, and corrosion resistance, extending its lifespan compared to bare galvanized sheet.
Easy to Clean: The smooth paint surface resists dust and can be easily washed clean by rain.
3.What are the potential considerations for galvanized coil (color-coated steel) booths?
Weight: Heavier than aluminum alloy booths of similar size, this slightly affects mobility. However, this can be addressed through strengthening the chassis and axles during design.
Insulation/Heat Retention: Metal itself is a good conductor of heat. If the booth requires built-in air conditioning or is used in extremely cold regions, it is usually necessary to fill the walls with insulating materials such as polystyrene (EPS) or polyurethane (PU) foam, creating a "sandwich panel" for optimal insulation.
Appearance: While color-coated steel panels appear attractive, they may lack the high-end quality of more elaborately designed aluminum-plastic panels or preservative wood. However, for most practical mobile booths, their appearance is perfectly adequate.
4.What are the advantages and disadvantages of galvanized coils compared to color-coated galvanized coils?
Advantages: Low cost, high strength, corrosion resistance, durability, and mature technology. Disadvantages: Heavy, requiring additional insulation for standard single-board panels.
5.What are the advantages and disadvantages of galvanized coils compared to aluminum alloys?
Advantages: Lightweight, corrosion-resistant, aesthetically pleasing, easy to process (bending, etc.)
Disadvantages: High cost, relatively low strength, slightly poor impact resistance
