　　S-Glass Fiber: High-strength glass fiber with 30-40% higher tensile strength than E-glass fiber. It excels in high-temperature resistance, impact resistance, and fatigue resistance, making it ideal for heavy-duty industrial scenarios such as high-voltage power transmission line maintenance, offshore platforms, and chemical plants. For customers searching for "heavy-duty fiberglass insulated ladder" or "high-voltage resistant fiberglass ladder," S-glass fiber products are the optimal solution. Diyu Electric’s industrial-grade series uses S-glass fiber to meet the high-load and harsh environment needs of professional users.

　　1.2 Distinguish Resin Matrix Performance

　　Polyester Resin: Cost-effective and fast-curing, it is suitable for mass-produced standard ladders. It has natural UV resistance, making it suitable for outdoor use. However, it is relatively brittle and less impact-resistant, so it is recommended for light to medium-duty applications. For buyers focused on budget, "polyester resin fiberglass ladder" is a common search term, and Diyu Electric’s entry-level series offers reliable polyester resin products at competitive prices.

　　Epoxy Resin: High-performance resin with superior adhesion, impact resistance, and chemical corrosion resistance. It is suitable for harsh environments with acid, alkali, or solvent exposure, but it requires UV stabilizers to prevent yellowing outdoors. Epoxy resin ladders are the first choice for professional users, corresponding to search keywords like "epoxy fiberglass insulated ladder" and "chemical-resistant fiberglass ladder." Diyu Electric’s premium series uses UV-stabilized epoxy resin, balancing high performance and weather resistance.

　　2. Verify Compliance with International Safety Standards
