Hefei SENOTECH New Materials Co., Ltd is proud to introduce our Duplex 2205 Matte Black Frameless Glass Railing Base – a premium solution designed for demanding marine and coastal environments. Engineered with core-drilled precision and complete with high-grade gaskets and bolts, this railing base delivers exceptional saltwater resistance without compromising on aesthetic elegance. As a trusted supplier since 2020, we combine robust material science with meticulous craftsmanship to provide a railing system that meets the rigorous standards of international projects across North America, Europe, Oceania, and beyond.
The base is crafted from Duplex 2205 stainless steel, a super-duplex grade known for its superior strength and outstanding resistance to chloride stress corrosion cracking. The matte black finish not only adds a modern, sophisticated look but also provides an additional layer of protection against UV and harsh weather. Each unit is supplied with pre-installed stainless steel bolts and EPDM rubber gaskets to ensure a watertight seal and vibration-free mounting. Whether you are installing a glass balustrade for a seaside villa, a luxury yacht deck, or a commercial pool surround, this product is built to last.
Key Features & Technical Specifications
- Superior Corrosion Resistance: Duplex 2205 offers a pitting resistance equivalent number (PREN) of ≥35, making it ideal for saltwater and chlorine-rich environments.
- Core Drilled Design: The base features a precision-machined core hole for seamless integration with glass panels – no exposed clamps or covers.
- Load-Bearing Strength: Tested to withstand up to 250 kg per linear meter (safety factor ≥2.5), suitable for both residential and commercial handrail applications.
- Matte Black Coating: A durable electrostatic powder coating that resists chipping, fading, and scratching; color consistency guaranteed across batches.
- Complete Hardware Kit: Includes stainless steel bolts (316 grade) and pre-shaped EPDM gaskets – no additional sourcing required.
- Universal Fit: Compatible with glass thickness from 10 mm to 21.52 mm (adjustable with optional shims).
- Easy Installation: Pre-assembled base body with threaded inserts, reducing on-site labor time by up to 30%.

Why Choose This Duplex 2205 Railing Base?
The combination of duplex stainless steel and matte black coating creates a product that outperforms standard 304 or 316 grades in saltwater. Many coastal projects experience pitting within two years using ordinary stainless steel; our Duplex 2205 base resists attack even after prolonged exposure to salt spray and humid environments. The core-drilled design eliminates sharp edges and provides a sleek, uninterrupted glass surface – perfect for modern architecture where clean lines are paramount.
Additionally, the included gaskets and bolts are pre-engineered to reduce installation complexity. The base comes with threaded holes for direct bolting to concrete, steel, or timber substrates. A simple three-step process – drill, insert bolt, tighten – secures the glass panel firmly. This significantly lowers the risk of improper installation and extends the lifespan of the entire railing system.

Frequently Asked Questions (FAQ)
Q1: What glass thickness does this base support?
A: Our standard base fits glass panels from 10 mm to 21.52 mm. For thicker or laminated glass, we can provide optional shims or modify the base design. Please specify the glass thickness when ordering.
Q2: Is the matte black coating durable outdoors?
A: Yes, we apply a high-quality electrostatic powder coating that withstands UV radiation, salt spray, and temperature fluctuations. The coating has passed 500+ hours of salt spray testing with no blistering or delamination.
Q3: Can I install this base on an existing concrete deck?
A: Absolutely. The core-drilled design requires a pre-drilled hole in the substrate (concrete, steel, or wood). We provide detailed installation drawings and recommend using a diamond core drill bit for concrete. Our bolts are designed to anchor securely.
Q4: What is the maximum spacing between bases?
A: For safety and structural integrity, we recommend a maximum center-to-center spacing of 1200 mm (4 ft) for residential use and 1000 mm (3.3 ft) for commercial projects. This ensures the glass panel remains stable under load.
Q5: Do the gaskets need replacement over time?
A: EPDM gaskets have excellent weather resistance and typically last 10–15 years under normal conditions. They can be replaced easily if needed. We stock replacement gaskets for all our base models.
Q6: Can I get a sample before bulk order?
A: Yes, we offer free samples (shipping cost applies) for serious buyers. Please contact our sales team with your shipping details and project quantity. Standard sample lead time is 3–5 working days.
Q7: How do I clean and maintain the matte black finish?
A: Use a soft cloth with mild soap and water. Avoid abrasive cleaners or metal brushes. For coastal environments, rinse with fresh water periodically to remove salt deposits. This preserves the coating’s appearance.
Q8: What is the minimum order quantity (MOQ)?
A: Our MOQ is 50 units for standard sizes. For customized dimensions or colors, MOQ may be higher. We offer flexible packaging options (bulk or individually boxed) according to your requirements.
