Staircase Glass Railing System: Complete Guide to Materials, Installation, and Pricing

Structure Components and Base Rail Specifications

• Base Rail Material and Dimensions: Full-length aluminium bottom rail available in 121x45mm, 100x45mm, and 80x40mm profiles. The rail follows the staircase angle continuously to ensure proper alignment and provide structural support for glass panels.
• Bracket Material and Grade: SS304 grade stainless steel brackets (also known as Bulister) installed at the base. SS304 is marine-grade stainless steel that provides corrosion resistance suitable for both indoor and outdoor staircase applications.
• Assembly Method: Mechanical nut-bolt fixing system eliminates the need for welding, glue, or silicon. This approach allows for easier installation, maintenance, and component replacement if needed.

Glass Panel Specifications and Wastage Calculation

• Laminated Safety Glass: Available in 5+5mm (11.52mm total thickness) and 6+6mm (13.52mm total thickness) configurations. Laminated glass consists of two glass layers bonded with a polyvinyl butyral (PVB) interlayer. If breakage occurs, the interlayer holds fragments together, preventing dangerous shards. Recommended for high-traffic staircases and commercial applications.
• 12mm Clear Toughened Glass: Single-pane toughened glass that undergoes heat treatment to increase strength. Provides maximum clarity and transparency while meeting safety standards. Suitable for applications where maximum visibility is a priority.
• Glass Wastage Calculation for Staircases: Staircase railings require 20% glass wastage to account for complex cuts, angles, and fitting requirements. This wastage is automatically factored into the price calculation. This same calculation logic applies to all staircase glass railing systems worldwide.
• Template Requirements: Customers must provide 8-10mm plywood or MDF board templates that match the exact staircase dimensions and angles. These templates ensure accurate glass cutting and proper fitting.

Handrail Profile Dimensions and Finish Options

• Standard Handrail Profiles: 25x25mm square aluminium handrail, 38x38mm round or square aluminium handrail, and 50x50mm round or square aluminium handrail. These sizes provide comfortable grip and visual presence suitable for staircase applications.
• Ultra-Slim Handrail Options: 19x19mm aluminium or stainless steel square profile, and 13x12mm aluminium or stainless steel profile. These options minimize visual obstruction while maintaining functionality, ideal for modern interior designs.
• Stainless Steel Handrail Finishes: Available with powder coating or PVD (Physical Vapor Deposition) finishes. PVD options include rose gold, matt black, gold, and brushed gold. These finishes provide durability and resistance to wear in high-traffic staircase environments.
• Aluminium Handrail Finishes: Can be powder coated in custom colors based on project requirements. Powder coating provides color matching options for interior design schemes and building aesthetics.

Bracket System and Base Rail Components

• SS304 Bracket Specifications: Marine-grade stainless steel brackets (also known as Bulister) provide corrosion resistance necessary for staircase applications. These brackets are installed at the base to secure glass panels and connect to the bottom rail system. Suitable for both indoor and outdoor staircase environments.
• Bottom Rail Function: The full-length aluminium base rail follows the staircase angle to ensure proper alignment and provide structural support for glass panels. Available in three profile sizes (121x45mm, 100x45mm, 80x40mm) to match project requirements and load specifications.
• Mechanical Fixing System: The nut-bolt assembly method eliminates welding, glue, and silicon. This approach allows individual components to be removed and replaced without affecting the entire system. Fasteners can be tightened if loosening occurs over time, and the system accommodates adjustments if settling occurs.

Hardware Package Contents and Anchor Bolt Requirements

• Hardware Package Components: The standard hardware package includes wall connectors for attaching the railing to building structures, 180-degree connectors for straight sections, and 90-degree connectors for corner and angle applications. These components are included in the package rate calculation.
• Anchor Bolt Specifications: Anchor bolts are installed at a rate of one bolt per two running feet (approximately every 600mm). These bolts secure the base rail to the concrete or structural surface, ensuring stability along the staircase. Anchor bolt costs are included in the package rate.
• Installation Charges: Standard installation includes basic installation work along the staircase. Additional charges may apply for complex angles, shifting, lifting between floors, or site-specific requirements that require extra labor or equipment. Installation costs are included in the package rate.
• Template Requirements: Customers must provide 8-10mm plywood or MDF board templates that accurately represent the staircase dimensions, angles, and any curves or transitions. These templates are essential for precise glass cutting and proper fitting. Template preparation is the customer's responsibility and should be done before glass fabrication begins.

Pillar/Bracket System and Stud Supports (Recommended for Staircase)

• SS304 Pillar/Bracket System: SS304 stainless steel pillars or brackets (also known as Bulister) provide additional structural support for staircase glass railings. These are installed every 3 steps (approximately every 2.5 feet) along the railing length. For a 6-7 feet glass section, typically 3 pcs are required (2 at corners + 1 in the middle). Available in 150mm and 200mm sizes. These are SS304 grade only and can be powder coated in wooden or plain finishes. Recommended for staircase applications.
• Stud Side Support System: Vertical studs are installed on both sides of the staircase to provide lateral support for glass panels. Available in 50mm and 38mm sizes. Average installation: approximately 1 location per RFT. For 6-7 feet glass: 3 locations × 2 pcs each (both sides) = 6 pcs total. These studs are installed vertically and provide stability along the staircase length. Recommended for staircase applications.
• When to Use Pillar/Brackets and Studs: Pillar/brackets are highly recommended for all staircase railings as they provide critical structural support, especially for longer spans and high-traffic areas. Studs are recommended for enhanced lateral stability and are particularly useful for wider staircases or where additional support is desired. Both systems work together to ensure maximum safety and structural integrity. The calculator automatically calculates quantities based on your railing length.

Handrail Finish Options and Selection Criteria

• Stainless Steel Handrail Finishes: SS handrails can be finished with powder coating or PVD (Physical Vapor Deposition) treatments. PVD finishes include rose gold, matt black, gold, and brushed gold. These finishes provide exceptional durability and resistance to wear in high-traffic staircase environments.
• Aluminium Handrail Finishes: Aluminium handrails can be powder coated in custom colors based on project specifications. This allows for color matching with interior design schemes, building aesthetics, or brand colors. Powder coating finish options are available in wooden and plain finishes.
• Finish Selection Considerations: When selecting finishes for staircase railings, consider the interior design style, surrounding materials, maintenance requirements, and traffic levels. PVD finishes offer superior durability in high-traffic areas, while powder coating provides more color options for design coordination. Consider how the finish will complement other staircase elements like treads, risers, and surrounding walls.
