Among them, frosted glass, with its unique aesthetic appeal and privacy protection function, has become a popular choice in partition design. This article will systematically introduce the installation steps for steel structure glass partitions and focus on analyzing the fixing techniques for frosted glass, helping you create safe, aesthetically pleasing, and practical space division solutions.
1. Pre-Installation Preparation: Material and Tool Checklist
1.1 Core Material Selection
Glass type: Tempered frosted glass (typically 8-12mm thick), always choose safety-tempered products.
Steel structure frame: Square steel tubes or custom profiles (common specifications: 50×50mm, 60×60mm).
Connectors: Stainless steel bolts, expansion bolts, specialized glass clamps.
Sealing materials: Silicone structural adhesive, foam strips, rubber padding blocks.
Auxiliary materials: Anti-rust paint, welding materials, grout.
1.2 Professional Tool Preparation
Measuring tools: Laser level, measuring tape, angle ruler.
Installation tools: Electric drill, impact drill, welding equipment.
Glass handling tools: Glass suction cups, adhesive gun, rubber mallet.
Safety equipment: Protective gloves, safety goggles, safety ropes.
2. Steel Structure Frame Installation: Laying a Solid Foundation
2.1 Positioning and Layout
Based on the design drawings, use a laser level to accurately mark the partition position lines on walls, floors, and ceilings. Special attention is required at this stage:
Verify consistency between on-site dimensions and the drawings.
Check the flatness and verticality of the base structure.
Mark all fixing point locations for columns and beams.
2.2 Main Frame Welding and Fixing
Prepare steel structure profiles according to cutting dimensions, with anti-rust treatment on cuts.
First, fix the ground beam to the floor using expansion bolts.
Install columns, ensuring vertical deviation ≤ 2mm.
Weld the top beam to complete the three-dimensional main frame structure.
Grind all weld points smooth and apply anti-rust paint.
The stability of the steel structure frame directly affects the safety and lifespan of the subsequent glass installation. Every connection point must be secure and reliable.
3. Frosted Glass Handling and Transportation: Special Considerations
3.1 Understanding the Properties of Frosted Glass
Compared to ordinary transparent glass, frosted glass has:
A specially treated surface creating a diffuse reflection effect.
Provides visual privacy while transmitting soft light.
The frosted surface is generally more fragile; avoid scratches from hard objects.
3.2 Safe Transportation and On-Site Storage
Use specialized glass suction cups and operate with at least two people.
During transportation, keep the frosted side facing up to avoid friction damage.
Store vertically on-site at an incline of 75-80 degrees.
Place soft materials at the bottom and store glass of different specifications separately.
4. Core Installation Techniques: Methods for Fixing Frosted Glass
4.1 Point-Supported Fixing Method (Modern Minimalist Style)
This method uses specialized connectors to fix the glass, suitable for large-area frosted glass partitions:
Precisely install stainless steel claws on the steel structure.
Position the frosted glass at the preset location and temporarily secure it with suction cups.
Pass bolts through pre-drilled holes in the glass (holes must be pre-drilled at the factory) into the claws.
Install sealing gaskets and tighten the fixing bolts.
Leave a 2-3mm expansion gap between adjacent glass panels.
Point-supported fixing creates a "floating" effect for frosted glass, offering strong visual impact but requiring precise measurement and fabrication.
4.2 Groove-Embedded Fixing Method (Traditional Reliable Method)
Fixes glass edges using U-shaped channels, suitable for spaces requiring high sealing:
Weld or bolt aluminum alloy channels onto the steel structure frame.
Lay rubber strips inside the channels to enhance cushioning and sealing.
Carefully embed the frosted glass into the channels.
Inject silicone structural adhesive from one side, ensuring full filling.
Install cover strips to improve aesthetics and fixing strength.
This method effectively protects glass edges, especially suitable for thinner frosted glass (below 8mm).
4.3 Clamp Plate Fixing Method (Flexible Adjustable Solution)
Uses metal clamp plates to fix glass from both sides, offering higher installation flexibility:
Determine clamp plate positions on the steel structure.
Place the frosted glass at the predetermined position.
Install the inner clamp plate for preliminary fixing.
Install the outer decorative clamp plate and symmetrically tighten the bolts.
Adjust the verticality and flatness of the glass.
Clamp plate fixing allows for some positional adjustment, suitable for projects with complex on-site conditions.
5. Key Points for Frosted Glass Installation
5.1 Direction Identification and Uniformity
Frosted glass has a smooth side and a frosted side. Before installation:
Confirm the required orientation of the frosted side per design.
Ensure all glass in the same area has the frosted side facing the same direction.
Typically, make inconspicuous marks on the corners of the frosted side.
5.2 Joint Treatment Techniques
The joints of a frosted glass partition directly affect its appearance:
Maintain uniform gaps between adjacent glass panels (typically 3-5mm).
Clean both sides of the joint on the frosted surface (pay special attention to dust in the frosted texture).
Insert foam rods as backing material.
Inject silicone sealant and use a specialized tool to create a smooth surface finish.
Carefully remove protective film to avoid adhesive contamination of the frosted surface.
5.3 Treatment of Special Areas
Corner areas: Use curved glass or specialized corner connectors.
Door sections: Use thickened frosted glass (typically 12mm) and install heavy-duty hinges.
Junctions with walls: Reserve expansion space and fill with flexible sealing materials.
6. Quality Control and Acceptance Standards
6.1 Installation Accuracy Check
Vertical deviation: ≤ 2mm/2m.
Horizontal deviation: ≤ 1.5mm/2m.
Glass surface flatness: No obvious waviness or deformation.
Joint width consistency: Error ≤ 0.5mm.
6.2 Safety Acceptance
All fixing points are secure; bolt torque meets design requirements.
Glass is free of cracks, chips, or edge breakage.
Tempered frosted glass must have 3C certification marks.
Edges and corners are smoothly finished with no exposed sharp parts.
6.3 Functional Testing
Sliding door leaves open smoothly and close tightly.
