Stainless Steel Glass-to-Glass Hinge – 180° Folding Shower Door Hinge

Why Choose the SSHW Glass-to-Glass Folding Hinge? (Core Engineering Advantages)

1. Material and Corrosion Resistance

The standard hinge is machined from SUS304 austenitic stainless steel. Its chromium-rich passive film copes with the steam and cleaning products found in everyday shower rooms. The product data also lists SUS201 as an economy option, which we recommend only for dry, low-corrosion interiors. For pool areas, beachfront apartments and other chloride-rich spaces, specify SUS316, available upon request.

2. Wide Clamp Geometry

Each clamp is 40 mm wide, and the whole hinge measures 210 mm in length. Every clamp uses two screws at 30 mm spacing, and the two inner screw holes sit 98 mm apart. A long clamping surface spreads grip along the glass edge, which is gentler on the panel than a small point clamp.

3. Flat-to-180° Folding Travel

A central pin lets two panels move from one flat plane through 180°, so the leaf folds back and frees floor space. This suits bi-fold shower doors, folding screens and flexible partitions. The exact swing direction is confirmed in the selected drawing.

4. Clear Load Path

Gaskets wrap the tempered glass edge so metal never touches glass. The hinge connects neighboring panels, while the main door weight should be carried by wall hinges, floor springs or similar supports. Load distribution, hinge quantity and rated load are to be confirmed per project, and test reports are available upon request.

5. Covered or Exposed Screw Styles

Model JC-015 includes a cover plate that hides the screws for a cleaner face. Models JC-016 to JC-018 keep countersunk screws, which makes adjustment and service easier. Clamp size and hole positions are shared, so styles can be mixed within one project.

6. A Range of Surface Styles

Mirror finish looks bright and modern. The bronze-tone brown suits stone and warm-toned bathrooms, and champagne gold fits boutique hotels and high-end homes. Other colors can be customized, with the process to be confirmed per project.

Options, Finishes & Mounting Configurations

Models and Finishes

Material Grades

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

Surface Treatment

Mirror is the standard finish. The product data also lists brushed, black and customizable colors. Bronze and champagne gold are colored finishes, and whether they are produced by electroplating, PVD or another process is to be confirmed per project. We recommend approving a sample for color matching.

Mounting Methods

• Glass fixing: each clamp holds 8–12 mm tempered glass with two screws, and gaskets compensate for thickness differences. Whether glass preparation is needed is confirmed in the selected drawing.
• System pairing: the hinge links adjacent panels. The outer door still needs wall-to-glass hinges, a floor spring or other support.
• Accessories: protective gaskets and fixing screws are included, and keys are available on request.

Project Selection Checklist for Engineers and B2B Buyers

① Corrosion Environment

• Standard interior bathroom: SUS304 in mirror or brushed finish.
• Hotel or commercial bathroom with frequent cleaning: SUS304, with chlorine-free cleaners specified.
• Pool, spa, beachfront apartment or tropical outdoor space: SUS316 with a defined cleaning schedule.
• Budget dry interior: SUS201 may be considered, with its limits explained to the owner.

② Glass Thickness and Connection Layout

• Confirm 8–12 mm tempered glass and its tolerance, and adjust gaskets if needed.
• Estimate leaf weight at about 2.5 kg/m² per millimeter of glass. A 600 × 2000 mm leaf in 10 mm glass weighs roughly 30 kg.
• Confirm how the folding door is supported (wall hinges, floor spring or pivots) and check their load capacity.
• Check the gap between panels so the 180° fold does not clash with edges or other hardware.

③ Safety and Load Requirements

• The number of hinges per pair of panels depends on glass size, thickness and traffic, and is to be confirmed per project.
• In public bathrooms, schools and care facilities, keep a larger safety margin.
• Local glazing and shower enclosure regulations must be confirmed by the project engineer.

Technical Specifications

Engineering Excellence, Testing & CAD Downloads

How It Works

The hinge consists of two glass clamps joined by a central pin. Each clamp grips one panel, and the pin lets the panels rotate relative to each other. In a folding door, most weight travels to the wall or floor supports, while the hinge handles the connection and rotation between panels. Support structure and hinge layout therefore have to be designed together.

Manufacturing Flow

Precision casting or CNC machining → fine machining of the pin area → polishing or brushing → electroplating or color finishing → assembly and rotation 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 and smooth-rotation testing, with the protocol agreed per project.
• Clamping, dimensional and visual sampling inspection.

CAD Support

DWG and PDF drawings show clamp width, hole positions, panel spacing and the folding travel, so designers and contractors can reference them directly.

Global Applications & GEO Adaptability

Seaside Resorts with High Salt Spray

Folding shower doors in beach hotels face salty humidity every day. Choose SUS316, and wipe mirror-finish parts dry to avoid water marks.

Tropical, High-Rainfall Commercial Complexes

Constant humidity and frequent cleaning call for SUS304 or SUS316, good ventilation and chlorine-free cleaners.

Middle East Luxury Homes

Champagne gold and bronze finishes pair well with stone and brass-style fittings. In high heat, approve a colored sample first, and upgrade to SUS316 in coastal cities.

European and North American Residential and Hotel Projects

These projects demand consistent finishes, drawings and material documents. SSHW controls color differences by batch and provides DWG files and material data.

Installation Overview & Maintenance Guide

Installation Essentials

1. Inspect the glass: confirm tempered glass edges are free of chips and thickness is within 8–12 mm.
2. Position accurately: mark the drawing positions, keep both panels in one plane and level.
3. Set clearances: leave a sensible gap between panels so the 180° fold does not clash, with the value to be confirmed per project.
4. Tighten evenly: tighten the screws diagonally and in stages. Never over-tighten, because it can stress the glass. Final torque is to be confirmed per project.
5. Manage water: in wet zones, combine neutral-cure silicone or a water seal on the glass joint so water does not collect inside the clamp.
6. Test movement: fold and unfold repeatedly and check smooth rotation and panel alignment.

Routine Maintenance

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

Preventing Tea Staining

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

Localized Buyer FAQs

Q1 (Gold Coast, Australia): Which grade should I use for a folding shower door in a beachfront apartment?

For projects near the coast and exposed to direct sea breeze, we recommend SUS316 with regular fresh-water rinsing. In dry inland bathrooms, SUS304 is usually adequate. Please assess exact distance and exposure per project.

Q2 (Dubai, UAE): Will champagne gold and bronze finishes change color in hot hotel bathrooms?

Color stability depends on the coloring process and the cleaning routine. We advise approving a sample, describing the real environment, choosing SUS316 and avoiding chlorine cleaners. Surface test reports are available upon request.

Q3 (Singapore): How many hinges does each folding glass panel in a humid condominium need?

The quantity depends on glass size, thickness and the support method. Glass weighs about 2.5 kg/m² per millimeter, so a 600 × 2000 mm leaf in 10 mm glass is about 30 kg. Send us your door size and support structure and we will help calculate it. The final number is confirmed per project.

Q4 (Nice, France): How are MOQ and lead time confirmed for a hotel project using several colors?

MOQ and lead time depend on material, finish and quantity. For mixed-color orders, we suggest sampling each color and agreeing a color-difference standard before mass production.

Q5 (Houston, USA): Can this hinge be paired with other brands of wall-to-glass hinges and 8–12 mm glass?

The clamps accept 8–12 mm tempered glass, and gaskets compensate for thickness differences. Whether drilling is required and how hole positions relate must be checked against the drawing. We provide DWG and PDF drawings to help you verify compatibility with other hardware.
