Stainless Steel Glass Door Hinge – 90° Double-Action Wall-to-Glass Shower Door Hinge

Why Choose the SSHW Stainless Steel Glass Door Hinge? (Core Engineering Advantages)

1. Corrosion Resistance Matched to the Environment

The standard glass door hinge is made from SUS304 austenitic stainless steel. Its chromium-rich passive layer protects the metal in humid bathrooms and general commercial interiors. The product data also lists SUS201 as an economy option, but we recommend it only for dry, low-corrosion interiors. For coastal resorts, pool areas and other chloride-rich sites, specify SUS316, which contains molybdenum and is available upon request.

2. Precision Manufacturing

Each wall-to-glass hinge is produced through precision casting or CNC machining, then finished by polishing, brushing or color treatment. The clamp is 35 mm wide, the overall length is 115 mm, and the screw spacing is 40 mm. This consistent geometry makes large hotel and residential batches easy to install and replace.

3. 90° Open-Inside and Open-Outside Movement

The internal pivot mechanism lets the door swing 90° in both directions. This double-action movement suits frameless shower doors, changing rooms and service passages where traffic flows both ways.

4. Load Path and Service Life

The glass clamp hinge grips tempered glass with two countersunk hex socket screws and protective gaskets, so metal never touches glass directly. Weight passes from the clamp through the pivot into the wall plate and the wall. Rated load and cycle life are to be confirmed per project, and test reports are available upon request.

5. Adjustable, Site-Friendly Installation

The L-shaped wall plate has three fixing holes and can be anchored to concrete, masonry or a backing plate in lightweight walls. Countersunk hex screws allow fine alignment of the door during installation.

6. Clean Architectural Aesthetics

Brushed finishes are discreet and resist fingerprints, mirror finishes look bright and clean, and matte black matches modern black bathroom fittings. Countersunk screws keep the clamp surface flush, which suits minimalist frameless glass door hinge designs.

Options, Finishes & Mounting Configurations

Models and Finishes

Material Grades

• SUS304: the recommended standard for interior bathrooms and commercial spaces.
• SUS316: recommended for seaside, swimming pool, spa and sauna areas. Available upon request.
• SUS201: economy grade for dry interiors only. It is not recommended for showers or coastal sites.
• Duplex 2205: special order only, evaluated per project.

Surface Treatment

Brushed, mirror and matte black are standard, and custom colors are available. The exact black process and coating specification are to be confirmed per project.

Mounting Methods

• Glass side: the clamp holds 8–12 mm tempered glass with two countersunk hex socket screws at 40 mm spacing. Whether glass preparation is needed is confirmed in the selected drawing.
• Wall side: the L-shaped plate is fixed with three screws, and anchors are selected for the wall substrate.
• Accessories: protective gaskets and hex screws are included. Keys and wall anchors are available on request.

Project Selection Checklist for Engineers and B2B Buyers

① Corrosion Environment

• ☐ Dry interior or standard bathroom: SUS304, brushed or matte black.
• ☐ Outdoor commercial or semi-open space: start with SUS304 and evaluate SUS316.
• ☐ Coastal, high-salt-spray or pool area: specify SUS316 and plan regular cleaning.
• ☐ Budget dry interior: SUS201 may be considered, but explain its limits to the owner.

② Glass Thickness and Substrate

• ☐ Confirm 8–12 mm tempered glass and its thickness tolerance.
• ☐ Estimate glass weight at about 2.5 kg/m² per millimeter of thickness. A 2000 × 800 mm door in 10 mm glass weighs roughly 40 kg, and in 12 mm glass roughly 48 kg.
• ☐ Identify the wall type (concrete, brick, metal stud, timber) to choose the right anchors. Lightweight walls need a backing plate.
• ☐ Check wall flatness so the plate sits flush.

③ Safety and Load Requirements

• ☐ The number of hinges depends on door height, glass thickness and traffic, and is to be confirmed per project.
• ☐ In public, child-care or elderly-care spaces, keep a safety margin.
• ☐ Local glazing and shower enclosure codes must be confirmed by the project engineer.

Engineering Excellence, Testing & CAD Downloads

How It Works

The hinge has three parts: a glass clamp, a pivot mechanism and an L-shaped wall plate. The glass weight travels from the clamp to the pivot, then to the wall plate and the wall. The load must end up in a sound substrate, which is why anchor selection and wall strength are critical on every glass door hinge installation.

Manufacturing Flow

Precision casting or CNC machining → fine machining of holes → polishing or brushing → color finishing → assembly and function check → packing.

Quality Control (available upon request)

• Neutral salt spray testing, referencing ISO 9227 or ASTM B117 methods.
• Spectrometer checks to verify SUS304 or SUS316 composition.
• Open-close cycle testing, with the protocol agreed per project.
• Dimensional and visual sampling inspection.

Global Applications

Seaside Resorts with High Salt Spray

Sea air carries chlorides that attack stainless steel surfaces. Choose SUS316 in mirror or brushed finish, and rinse with fresh water regularly.

Tropical, High-Rainfall Commercial Complexes

Constant humidity and condensation are the main challenges. SUS304 or SUS316 with good ventilation reduces pitting and water marks.

Middle East Villas and Modern Facades

Heat and dust make surface wear resistance important. Matte black and brushed finishes hide dust marks, and coastal cities should upgrade to SUS316.

European and North American Residential and Hotel Projects

These projects demand consistent finishes, drawings and compliance documents. SSHW supplies uniform batches, DWG files and test data.

Installation Overview & Maintenance Guide

Installation Essentials

1. Verify dimensions: confirm 8–12 mm glass thickness, glass size and hinge positions against the drawing.
2. Prepare the wall: make sure the wall is flat and solid, add backing where needed, and choose suitable anchors.
3. Set clearances: leave sensible gaps between the glass and the wall, floor and neighboring parts, typically 2–4 mm and to be confirmed per project.
4. Tighten screws evenly: tighten the hex screws alternately and in stages. Final torque is to be confirmed per project. Never over-tighten, because it can stress the glass.
5. Waterproof penetrations: seal wall plate holes in wet areas with neutral-cure silicone, and keep the waterproof membrane intact.
6. Test movement: open and close the door repeatedly and check alignment and smooth 90° swing in both directions.

Routine Maintenance

• Wipe with a mild detergent and a soft damp cloth, then dry.
• Avoid chlorine bleach, hydrochloric acid descalers and steel wool.
• In coastal or pool environments, rinse with fresh water monthly.

Preventing Tea Staining

Tea staining is a light brown discoloration caused by surface contaminants, and it is more common near the sea and in humid rooms. Prevent it by choosing SUS316, cleaning regularly, keeping carbon steel tools and iron dust away from the surface, and keeping the hinge dry.

Localized Buyer FAQs

Q1 (Perth, Australia): Should I choose SUS304 or SUS316 for a beachfront shower enclosure in Perth?

For projects close to the coast, especially in direct sea breeze, we recommend SUS316 with regular rinsing. In dry inland bathrooms, SUS304 is usually adequate. Please assess the exact distance and exposure per project, and confirm local glazing requirements.

Q2 (Sharjah, UAE): Will the matte black finish fade in high heat and humidity?

Durability of a black finish depends on the specific process and on cleaning habits. For Sharjah's hot, humid conditions we suggest SUS316, and we advise confirming the black process and approving a sample before bulk production. Surface test reports are available upon request.

Q3 (Miami, USA): Can this glass door hinge be used on a pool changing room door?

Pool areas contain chlorine and salt, so we recommend SUS316 and advise against SUS201. The number of hinges depends on glass weight and door height. Glass weighs about 2.5 kg/m² per millimeter, so send us your door size and we will help you calculate it.

Q4 (Marseille, France): What are the MOQ and lead time for a hotel order, and can colors be customized?

MOQ and lead time are confirmed per project based on material, finish and quantity. Brushed, mirror and matte black are standard, and other colors can be customized. We recommend sampling first, then moving to mass production.

Q5 (Jeddah, Saudi Arabia): Is this wall-to-glass hinge compatible with other brands of tempered glass and hardware?

It fits 8–12 mm tempered glass. Glass thickness tolerance and whether drilling is required must be checked against the drawing. We provide DWG and PDF drawings so you can verify compatibility with other glass hardware.
