Product Overview

A successful building enclosure depends on more than the panels alone. Panel dimensions, support positions, connection details, openings and perimeter flashings must work together to form a complete system.

The ZSJH Steel Sandwich Panel System combines metal-faced insulated panels with coordinated fixing and finishing components. It is suitable for new steel buildings, extensions, modular construction and selected refurbishment projects.

Each panel incorporates an insulation core bonded between metal facings. This composite construction brings the external finish, insulation layer and internal lining into one prefabricated component, helping simplify site assembly.

From the first panel schedule to the final corner trim, the supply package can be developed around approved drawings and the agreed project scope.

Designed Around Your Project

Coordinated Panel Layout

Panel lengths and installation direction can be planned around structural bays, door openings and window positions. An organized layout helps limit unnecessary cutting and keeps visible joints consistent across the building.

Application-Specific Insulation

Core material and panel thickness should reflect the building’s intended use. Project considerations may include indoor temperature, humidity, acoustic requirements and documented fire performance.

Rock wool, EPS, PU and PIR configurations can be discussed during specification review. Availability and suitability are confirmed for the selected panel product.

Compatible Surface Finishes

Facing materials and coatings can be selected to suit the external environment and internal operating conditions. Color and profile coordination also helps achieve a consistent appearance across walls, roofs and accessories.

Detailed Connections

Panel-to-panel joints are only one part of the enclosure. Base details, roof edges, corners and service penetrations also require compatible trims and seals to manage water and air leakage.

Product Configuration

A Coordinated Supply Package

Depending on the project scope, the panel package may include:

• Insulated wall and roof panels

• Internal partition panels

• External and internal corner flashings

• Ridge, verge and eave components

• Base trims and opening surrounds

• Compatible fasteners and sealing materials

• Panel layout and connection information

• Protective packaging for shipment

Coordinating these items early helps reduce mismatched components and missing finishing materials during installation.

Typical Applications

Manufacturing Facilities

Panel systems can form the external enclosure of production buildings and provide internal separation between designated operating areas.

Warehousing and Distribution

Coordinated wall and roof panels support consistent enclosure layouts across storage buildings, loading areas and distribution facilities.

Temperature-Controlled Spaces

Suitable panel configurations can be considered for refrigerated storage and processing environments. Joint sealing, vapor control and penetrations require particular attention.

Modular and Prefabricated Buildings

Project-sized panels can be incorporated into site offices, accommodation units and auxiliary buildings, subject to the approved building design.

Building Extensions and Renovations

Sandwich panels may be used to enclose new extensions or replace selected existing envelope elements after the supporting structure and connection conditions have been assessed.

Project Coordination with ZSJH Steel

ZSJH Steel supports coordinated steel-building supply, helping customers align enclosure requirements with the main structure and related components.

Our project discussions focus on:

• Drawing-based customization

• Panel and accessory compatibility

• Coordination with steel framing

• Inspection requirements agreed before production

• Packaging and delivery planning

• Installation guidance within the agreed supply scope

FAQ

Can the same panel be used for both roofing and walls?

Not automatically. Roof and wall panels may have different profiles, joints and installation requirements. The selected product must be suitable for its intended application.

How is the required panel thickness determined?

Thickness depends on the required thermal performance, core material, operating conditions and selected panel system. It should be specified using product data and project requirements.

Are sandwich panels the building’s main structural frame?

Generally, they form the building enclosure and transfer specified loads to supporting members. They should not be treated as a replacement for the main structural frame unless an engineered system specifically permits this.

Can openings for doors, windows and equipment be included?

Yes, openings can be coordinated in the panel layout. Reinforcement, support members, flashings and seals may be needed around openings, depending on their size and location.

Do all sandwich panels have the same fire performance?

No. Fire performance varies with the core, facings, joints, fixings and tested assembly. Any required classification must be supported by documentation for the specified product and installation.

What information helps you prepare a quotation?

Please provide the project location, building drawings, panel application, required quantities, insulation targets, finish preferences and delivery destination. If a specification is available, include it with your inquiry.
