INTUR: Rigid Intumescent Fire Seal Strips
Rigid types of Intumescent fire seals are most suitable for sever application where regular door maintenance is not possible. The PVC covering to the graphite intumescent seal protects from wearing out due to any mechanical damage to the seals.
At wedge we produce and supply different versions including fire only, fire & smoke, fire & acoustic, and fire & weather proof seals of Rigid Fire Seals depending on the end user requirements.
In the event of a fire the INTUR intumescent graphite seal expands multiple times its original volume and seals the gap around the door edges and joints to provide fire barrier and stop the passage of fire, smoke and hot gases. Surface Mounted Acoustic & Smoke Door Bottom Seals or Rebate Fit Acoustic & Smoke Door Bottom Seals are most suitable for the door bottom sealing. All fire and smoke seals are supplied with a self-adhesive backing tape as standard to facilitate quick and easy fitting. All the seals are Tested for 30 minutes, 60 Minutes, and 120 Minutes to BS 476 part 22 & 31.1. Smoke seals tested to EN1634-3 to 100, 000 open/close cycles.

wedge coil aluminium wire w-al99 is 99 % minimum specification. Aluminum (al) is used for deoxidizing and grain refining in steels. It is a strong deoxidizer. It is also used as nitride former and as an alloying agent. Its ability to scavenge nitrogen (n) from steel makes it a useful addition in drawing quality steels, especially for automotive applications. We at wedge have strong willingness to offer best quality steel raw materials. Along with refractoriesferro alloys are our one of the mostimportant flagshipproduct range.
aluminum (al) is being used as a deoxidizing element in steels for more than 100 years. Deoxidation of steel with al is common practice today. Al plays an important role in secondary metallurgy. It forms aluminum oxide or alumina (al2o3) alumina and decreases the amount of oxygen in the steel during the production of killed steels.metallic al is the most common addition agent.
at wedge we also supply other forms notched bars, shots, pigs, small ingots, chopped wire, briquettes along with convenient forms such as coiled machine fed wire. Purity of deoxidation grade of al is normally over 95 % with the main tramp elements being zinc, tin, copper, magnesium, lead and manganese.

what is passive fire protection?
passive fire protection are the systems made of non-combustiblefire resistant materials andcomponentsused to minimise damage to life and property by confining the fire and stopping spread of firefor sufficient time to permit the safe evacuation of all occupants of the premises untilthe arrival of the fire officers. The person responsible for fire safety also has a duty of care towards any members of the emergency services, e.g. Fire fighters, who may have to enter the premises during the course of a fire; in slowing the spread of flames, smoke and hot gases, passive fire protection also serves to ensure the building remains as safe as possible for entry in this situation.
passive fire protection is achieved by maximising use of fire resistantstructural and non structural building components and minimise use of combustible materials. Sealing of joints and concealed spaces with fire resistant sealant and other fire stopping materials.
what is fire resistance?
fire resistance is a thermo-mechanical property of a building componentthat reflects the performancein terms of stability, integrity, and insulation requirements for a stated periodagainst fire.
stability (load bearing capacity)
ability of a load bearing component to withstand fire exposure without any loss of structural stability.
integrity
resistance to penetration of flames, hot gases, and smoke.
insulation
resistance to temperature rise on unexposed face upto a maximum 180 degree c at any single point and average temperature of 140 degree c.
at wedge we produce high performance and low cost passive fire protection systems.
shellac is perfect for antique restoration, furniture finishing and refinishing, casework, architectural woodwork, toys and general woodworking.
shellac is widely used in the candy and confectioner's glazes and coatings, cosmetic, drug and food industry. It is the only finish that should be used on childrens furniture due to its non toxicity!
shellac is processed and sold as dry flakes and dissolved in ethanol to make liquid shellac, which is used as a brush-on colorant, food glaze and wood finish. Shellac functions as a tough natural primer, sanding sealant, tannin-blocker, odour-blocker, stain, and high-gloss varnish.
silica bricks are made of quartz stone material, the content of sio2 is more than 96%. The nature and craft process of silica bricks are closely related to the crystal transformation of sio2. The density is an important quality indicator of silica bricks. The density of silica bricks should be below 2.38 g/cm 3. The quality of silica brick should be below 2.35 g/cm3.
silica bricks have the excellent ability to resist acid slag and acid solution erosion. besides, silica bricks have good high temperature strength, high refractoriness under load about 1640-1680c, high softening point with temperature. Whats more, silica bricks are also featured with good heat conduction and the refractoriness is 16901730c
