PC Multi - wall Sheet types:
Twin-wall Rectangle-structure Sheet
3-wall Rectangle-structure Sheet
4-wall Rectangle-structure Sheet
4-wall Honeycomb-structure Sheet
5-wall D-structure Sheet
5-wall Honeycomb-structure Sheet
Multi-wall structure gives the sheets very good heat preservation performance,which can reduce the energy consumption upon temperature conditioning.Multi-wall sheets are more resistant to impact,suitable for the requirements of high standards engineering.
SPRING SIGN imports UV testing equipment from abroad,used to test the thickness of UV layer and uniformity of the layer,ensuring the service time of the sheets in harsh natural conditions,to provide customers with high quality UV SPRING SIGN sheets.
Twin-wall Rectangle-structure Sheet
Polycarbonate (PC)extruded sheet offers good thermal insulation properties and the impact resistance beyond other thermoplastic sheets.The twin-wall rectangular sheet is the most commonly used type of hollow sheet.Such sheet is easy to install,easy to process and has high transmittance.It is economic and commonly used in ordinary building lighting needs, such as plant day lighting roof,greenhouse,parking shed,etc.SPRING SIGN twin-wall sheet has single or double faced UV co-extrusion layers that are resistant to UV rays in sunlight.It is weatherproof and delays cracking and aging.SPRING SIGN twin-wall sheet comes in various thicknesses and multiple standard colors available for choice.
Applications
Awning,Skylights,Carport,Windows, Agricultural Greenhouse,Eco-Restaurant
3-wall Rectangle-structure Sheet
Better insulation performance is an obvious advantage of SPRING SIGN triple-wall rectangular sheet compared to the traditional 2-wall PC sheet.This feature makes it more suitable for installation with higher requirements for thermal insulation and energy saving.The triple-wall PC sheet has higher strength and bears more pressure and loads and support bigger installation purl in distance and span compared with the twin-wall sheet.It provides better support for light weighted structure and saves more costs of structure installation.SPRING SIGN offers single or double faced UV co-extrusion layers to protect the sheet so that it will better endure the climatic changes and damage to the sheet by UV rays for longtime.SPRING SIGN triple-wall rectangular sheet comes in various thicknesses and various thicknesses and multiple standard colors available for choice.
Applications
Agricultural greenhouses,ecological restaurants,architectural daylighting, large carport,side windows,sunroof skylights,stadiums,light partitions
4-wall Rectangle- structure Sheet
The multiwall cavity structure of the four-wall rectangular sheet provides it with excellent bearing capacity.The excellent thermal insulation property is more important.It gains a decrease of the heat conductivity (k value)by20% compared to the triple-wall sheet with the same thickness.In addition to a light and compact structure,the sheet is more energy efficient and environmentally friendly and has enhanced bearing capacity.Addition of the coating whose external surface is easy to clean and has anti-dropping function at the lower layer is allowed so that its transparency can be maintained.It ensures the transmittance of visible light and infrared light while blocking UV rays so as to protect plant growth.The sheet comes in various color and thickness options.
Applications
Agricultural greenhouses,ecological restaurant,large-scale daylighting ceiling, light partition,carport
4-wall Honeycomb-structure Sheet
The compact and dense honeycomb structure offers better bearing capacity than other structures.SPRING SIGN produce the high-quality sheet by making use of the advantages and the bionic principles.The internal multiwall cavity and side wall increases the sound and thermal insulation of the sheet.Moreover,it has the strength approximately two times that of ordinary sheets while maintaining low height.SPRING SIGN patented sheet is internally satin-finished,which solves solitary light phenomenon under strong light after sheet installation.It makes the surface softer and creates more comfortable lighting environment.The sheet comes in transparent and semi-transparent (milk white)as the standard colors, other colors can be customized.
Applications
Stadiums,commercial,industrial buildings,roofs, building upright partitions,high-speed rail stations, terminals
5-wall D-structure Sheet
The oblique internal support structure greatly improves loading capacity and tensile capability of SPRING SIGN star-shaped five-wall sheet.It is suitable for large-span installation and is an ideal choice for building daylighting with high requirements for installation strength.The sheet is relatively safer and suitable for use in large-scale daylighting and is the preferred sheet of engineering projects.SPRING SIGN controls the transmittance amount of light rays with color and transparency so as to create more comfortable indoor environment.The standard colors include transparent and milk white (semi-transparent).Special colors can be customized.Single or double faced UV co-extrusion layers can be provided.Various thickness options are available.
5-wall Honeycomb- structure Sheet
SPRING SIGN five-wall honeycomb sheet is the upgraded sheet of the same type developed by SPRING SIGN.It better reflects the thermal properties of these structural sheets.The heat conductivity (k value)can be astonishingly 1.3 so that the indoor temperature can be controlled easier.Use of it in large space can effectively save the temperature control effects such as air conditioning.It offers more rigid structure and higher tensile strength,bearing capacity and impact resistance than that of equivalent sheets.SPRING SIGN patented sheet is internally satin-finished,which solves solitary light phenomenon under strong light after sheet installation.It makes the surface softer and creates more comfortable lighting environment.The sheet comes in transparent and semi-transparent (milk white)as the standard colors. Other colors may be customized.
Applications
Building,airport,industrial daylighting roof,large high-speed rail station, garage,canopy,indoor partition
The coating of SPRING SIGN anti-drop sheets is first-class material of organic silicon anti-drop materials,which are cured on the surface of sheets after pre-clean treatment.The adhesion is strong and not easy to be wiped off.The bottom surface of these sheets have small contact angle with water drops.So only tiny moisture is produced, which is quickly diverged down the ramp of the sheets,SPRING SIGN sheets have remarkable dripping resistant performance.
