Double-Opening SMC Fiberglass Rectangular Septic Tank Lid

The BAOGAI Trust Factor: Corporate Strength & Technical Precision

• China’s Only Listed Manufacturer: BAOGAI stands alone as the only publicly listed company in the composite manhole cover sector. This status ensures complete financial transparency, rigorous third-party audits, and a commitment to quality that protects your reputation. When safety is non-negotiable, choose a partner with the highest level of corporate accountability.
• Heavy-Duty SMC Molding Center: C250 rated covers demand exceptional structural integrity. Our advanced SMC press line features high-tonnage molding presses specifically calibrated for large-format, load-bearing components. This ensures our 1500 x 587 mm C250 series achieves uniform density, optimal fiber orientation, and zero internal voids—critical factors for withstanding repeated heavy traffic loads. Our “factory-direct” tooling enables rapid custom branding with significantly lower costs and faster delivery than typical trading partners.

Product Overview

The BAOGAI 1500 x 587 mm Double Opening SMC Fiberglass Rectangular Septic Lid is a heavy-duty access solution rated C250 (EN124) for roadway applications. Constructed from high-performance Sheet Molding Compound, it withstands 25-tonne wheel loads from trucks and buses while weighing 70% lighter than cast iron. The extended 1500mm length provides continuous access for drainage channels, cable trenches, and utility ducts beneath public roads, loading bays, and industrial zones.

MAIN PARAMETER

Key Advantages

• Certified C250 Load: 250kN test load certified for heavy truck and bus traffic on public roadways.
• Silent “No-Clang” Performance: Thanks to our in-house precision molds, the cover-to-frame tolerance is minimal. This ensures a silent experience when cars drive over—making it the preferred choice for high-end residential estates and shopping plazas.
• Permanent Anti-Theft Protection: With zero scrap value, SMC covers eliminate the motive for theft. This protects your site from the liability of open pits and saves municipalities from the high cost of replacement.
• Maintenance-Free Service: Never rusts, corrodes, or requires painting. Unaffected by road salts and de-icing chemicals.
• Large 1500 mm Access: Provides full personnel access to utility vaults and equipment chambers.

Target Applications

FAQ

Q1: Can a 1500mm long composite cover really handle C250 traffic loads without deflecting?

A: Absolutely. Our 1500 x 587 mm C250 trench covers feature an engineered ribbed-back design with longitudinal reinforcement that distributes loads efficiently across the entire span. The high glass content SMC formulation provides exceptional stiffness-to-weight ratio, ensuring zero permanent deflection under 25-tonne loads. Independent testing confirms compliance with EN124 C250 requirements.

How do you install such a long cover without special equipment?

A: The cover is designed for one-person installation. Multiple recessed lifting points are strategically positioned along the length to ensure balanced handling. No mechanical lifting equipment is required—a significant advantage over cast iron equivalents that can exceed 120kg and require crane lifting.

Q3: Is the C250 certification provided for this large format?

A: Yes. As a publicly listed company, we provide full certification documentation including load test reports specific to the 1500 x 587mm format. Third-party witnessed testing can be arranged upon request.

Q4: How does the cost compare to cast iron trench covers?

A: While the unit price may be comparable, the total installed cost is significantly lower with SMC due to:

• Reduced transportation costs (70% lighter = more covers per container)
• o-person installation (no crane required)
• Zero maintenance (no painting, no corrosion repairs)
• No replacement costs due to theft
