1.How to choose suitable corrugated board according to different usage scenarios?
For outdoor applications (roofs, exterior walls, and sheds): Focus on weather resistance, UV resistance, and rain/humidity resistance, prioritizing the elimination of coatings suitable only for indoor use (such as acrylic coatings).
For indoor applications (warehouse partitions, display cases, and interior walls): Outdoor weather resistance is not a concern. Focus on decorative effects and cost, choosing cost-effective coatings (such as acrylic coatings and standard PE coatings).
2.How to choose corrugated board based on durability requirements?
Short-term use (3-5 years, such as temporary factories and transitional buildings): PE coating (low cost, meets short-term needs);
Medium-term use (8-12 years, such as conventional factories and commercial ancillary buildings): SMP coating (balances durability and cost);
Long-term use (15-20 years+, such as high-end buildings, landmark projects, and high-maintenance roofs): PVDF coating (one-time investment, reduces future replacement costs).
3.How to choose the type of corrugated board according to decorative requirements?
For "rich colors/personalization": PE coating (customizable in matte, glossy, and special colors such as wood grain and stone), acrylic coating (bright colors, indoor use only);
For "long-term color stability": PVDF coating (primarily based on inorganic pigments, no noticeable fading for 15 years), SMP coating (better color retention than PE).
Note: Because PVDF coating relies on inorganic pigments for weather resistance, its color options are relatively limited (mostly standard colors such as iron gray and sea blue, and customizing special colors is costly).
4.How to choose corrugated board according to special functional requirements?
Self-cleaning properties (e.g., difficult-to-clean roofs, rainy areas): PVDF coating (smooth surface, rainwater washes away dust and stains, reducing manual cleaning).
Scratch resistance (e.g., roofs subject to bumps and bumps during installation, or where people move around): SMP coating, PVDF coating (harder than PE, less susceptible to scratches).
Chemical resistance (e.g., chemical plants and food processing plants, potentially exposed to oils, acids, and alkalis): PVDF coating (resistant to solvents, acids, and alkalis, and less susceptible to corrosion and dissolution).
5.In order to avoid "over-selection" or "cost waste", how to choose the right corrugated board?
Limited budget + short-term use: Choose PE coating for ordinary inland factories and temporary buildings (meets basic outdoor needs and is the lowest cost).
Medium budget + medium-term durability: Choose SMP coating for conventional commercial buildings and temperate coastal projects (50% more durable than PE, only 10%-30% more expensive).
Sufficient budget + long-term durability / extreme environments: Choose PVDF coating for high-end buildings, coastal areas, and chemical environments (a one-time investment avoids the cost of replacement every 3-5 years, making it more cost-effective in the long run).
