Roof bolts / studs are mechanically point anchored within the rock using 3 leaf bail-type expansion shells attached to the inserted end of the bolt. Expansion shells are supplied screwed onto the end of the rock tendon and are inserted into the hole. When tension is applied to the tendon the tapered plug within the shell forces the leaves to move outwards, thus wedging them against the walls of the borehole. This means that the mechanical bolt is functional immediately on installation. In many applications the installation is post-grouted for additional stability. The complete rock bolt assembly includes the threaded bar, bearing plate (washer), nut, seat and expansion shell.
Advantages of the product:
• Mechanical Anchors provide immediate active support.
• Wide choice of combinations to meet specific support requirements.
• Can be post grouted.
• The wedge and leaf arrangement provides parallel contact with the hole sides.
• Up to 4 mm range in hole diameter can be tolerated (depending on the choice of shell).
UV resistant cable ties are the ideal option for high ultraviolet environments. These ties are specifically manufactured to be used for continuous or extended exposure to outdoor use and UV light specially. UV resistant cable ties are made by incorporating stabilizers in the nylon resin, adding to the functionality that they provide. They are produced to be considered a weather resistant grade, with enduring additional UV light being the most important added benefit. In addition to being UV resistant, these cable ties are UL94V-2 Rated, meaning they are conform to the standards set by UL in terms of standards for safety of flammability of plastic parts.
Feature:
1-High level of strength
2-Very robust construction
3- Very reasonable rates
4-Strong structure
5-Suitable for a variety of applications
6-Standard and Heavy Duty Tensile Strength
7-Weather resistant grade for Ultraviolet (UV) light (black color only)
Description:
Guaranteed unbreakable malleable iron frame with a fast action twin start rolled acme thread. The steel swivel shoe applies an even pressure, even on angled surfaces, whilst the tommy bar will bend before the frame can become over-stressed
Ideal for metal and woodworking applications, these clamps are most popular and widely used G-clamps
It is used particularly for metalworking and fabrication work where very high clamping force is needed.
It has drop - forged steel frame for strength and durability.
Swivel shoe helps clamping on uneven surface.
It has twin-start acme cold rolled thread for faster operation. its fused steel handle will bend before the clamp can be overstressed.
Manufactured from drop forged ribbed anti-twist frame steel suited to fabrication and welding applications, etc. Resistant to rusting and weld spatter.
