1.What are the main application scenarios?
Stage Backdrop and Side Panels:
Used for constructing large-scale themed backdrops, stage back panels, and side wing partitions. Their smooth surface and rich colors allow for direct use or serve as a base for easy painting, poster application, and sticker installation.
Stage Platform (Tabletop):
Thick, high-strength color-coated steel sheets (usually profiled or composite panels) are laid on the stage's steel frame to provide a sturdy floor for the performance area. Particularly suitable for stages requiring a flat, smooth surface.
Props and Scenery Production:
Due to their ease of cutting, bending, and securing, they are commonly used to create large props, abstract scenery, passageways, arches, etc. The metallic texture itself is also a decorative style.
Temporary Structures and Fences:
Used for constructing backstage functional areas (dressing rooms, equipment rooms), auditorium canopies, and perimeter fencing, providing isolation, shelter, and basic weather protection.
2.What are our core strengths?
Low cost and high cost-effectiveness: Compared to wood and aluminum sheets, color-coated steel sheets offer a more competitive price, making them suitable for budget-sensitive performances and temporary events.
Lightweight and high-strength: Relatively lightweight yet high-strength, facilitating transportation, handling, and rapid installation.
Easy construction: Can be cut and drilled on-site, and quickly secured to steel structures using screws, rivets, or special clips, resulting in extremely high assembly and disassembly efficiency, ideal for performances with tight deadlines.
Clean appearance: Offers a uniform, clean look and a variety of color options, achieving a basic aesthetic effect without additional decoration.
Reusable: High-quality sheets can be disassembled and reused multiple times for different performances, reducing long-term costs.
3.What are the key considerations and limitations?
Fire Safety (Top Priority!):
The stage is a critical area for fire safety. Class A fire-resistant composite core panels, such as color-coated steel rock wool sandwich panels, must be used. Flammable polystyrene foam sandwich panels are strictly prohibited.
Even when using single-layer color-coated panels, the organic coating on the surface will burn under open flame; therefore, they must be kept away from high-temperature heat sources (such as lighting) and equipped with adequate fire-fighting facilities.
Structural Safety:
The color-coated panels themselves are not load-bearing and must be attached to a sturdy steel frame or keel. The structural design must be calculated by professionals to ensure wind resistance, pressure resistance, and stability.
When used as a platform, panels of sufficient thickness and rigidity must be selected, and dense underlayment must be ensured to prevent sinking or noise when actors step on them.
Edge Treatment and Protection:
The edges of the cut steel plates are very sharp and must be ground and edge-wrapped to prevent scratches to staff and actors.
4.What are the recommendations for material selection and usage?
Substrate Selection: For outdoor or humid environments, aluminum-zinc coated substrates are recommended for better corrosion resistance.
Coating Selection: PVDF is recommended for outdoor use; polyester can be used for short-term indoor use.
Form Selection:
Single-layer profiled sheet: Used for platforms and ceilings; high strength.
Sandwich panel: Used for feature walls and fencing; good thermal and sound insulation; high flatness; must use Class A fire-resistant core material.
5.What are the core principles of using pre-painted rolls in the stage construction industry?
Color-coated rolls are an "economical and practical multi-functional panel" in the stage construction industry. They are particularly suitable for large music festivals, touring concerts, exhibitions, temporary celebrations, and other occasions requiring rapid setup and dismantling.
The core principle is to fully utilize their economic, lightweight, and quick-assembly advantages while ensuring safety (especially fire prevention and structural integrity). Before official use, it is essential to fully communicate with stage structure engineers, stage designers, and material suppliers to select and install the material based on the specific stage design, usage environment, and safety regulations.
