Plano-Concave Lenses |
 |
|
| Plano-Concave Lenses Plano-Concave Lenses have a negative focal length and is typically used to cause a collimated beam to diverge as in a Galilean type beam expander or Telescope. Because the spherical aberration of the Plano-Concave is negative, it can be used to balance the aberration of other lenses. |

TRELLIS NETTING |
|
|
Trellis netting is a solid versatile plastic mesh, designed to provide both vertical and horizontal support to climbing plants or vegetables and horizontal support to long-stemmed flowers.
Used vertically, it can support crops like beans and peas till the crops are at their heaviest and ready for harvesting.
Laid horizontally, Plant support Net in layes becomes a fairly effective guide to space-keeping in planting. Successive layers can be fixed at brackets with the continuing growth of plants. This method has been widely adopted by flower growers especially for long-stemmed ones like chrysanthemum, freesia and carnation.
Trellis netting is a clean, economical, harmless to delicate stems or leaves, and quite easy to fix. At the end of planting season, it can be quickly dismantled and rolled up for subsequent use.
All climbing plants and vegetables and long-stemmed flowers require support to encourage healthy growth. Trellis netting can be used horizontally or vertically. It is used horizontally by stretching it between uprights - for example, in the herbaceous border for delphiniums, chrysanthemums, alstroemerias, or in the vegetable plot for broad beans. It is used vertically on a frame or against a wall for runner beans, sweet peas, garden peas, cucumbers and clematis.

Welded Gabions |
|
|
Welded mesh gabions are filled on site with hard and durable stones to form mass of gravity retaining structures. Due to their inflexibility, welded gabions are generally not considered suitable in areas susceptible to differential settlement, or in water courses.
Our welded gabions are available in a variety of wire diameters and unit sizes to meet project requirements.
In common with all gabions during installation, all welded units need internal bracing wires to be overfilled to allow for settlement of the granular rock fill.
Gabions are delivered on site in folded condition (flat-packed) on a pallet. All verical joints are factory fitted which increases the quality and speed of assembly on site. Depending upon the configuration of the Gabion, the base and lid panels are connected with 1 horizontal and helical. The accesories (bracing ties and joining pins) are prefabricated and adjusted to the Gabion type. To close the base and lids additional spirals are neccessary.
Take a Gabion from a pallet and cut the securing brace. Lift the accesories and pull the Gabion untill full length is reached. Close the base helically and fold the ends 90° inwardly. Now the spirals won't detach when moving and turning the Gabion. This will also prevent sharp end and injuries. This can be done with standard pliers. Now turn over the Gabion.
For large lengths, the Gabions should be connected as to form a monolithic structure. Prefabricated joining pins are provided for each Gabion. Simply grasp the 2 spirals then push them into each other. Place the joining pin into the section and push it downwardly. Care must be taken that the head of the pin faces should be inward. This must be done for security reasons and will prevent vandalism. The joining must be done at both sides.
As to prevent heavy deformation caused by filling the Gabions, bracing ties are included in each Gabion. Depending upon the height of the gabion, these are placed at 1/3 + 2/3 or 1/2 of the height.
Now start filling the first part of the Gabion.
Bracing ties are placed 4 meshes from the sides and around the weld. If not, the weld can break or the bracing tie can move. Repeat this principle untill the Gabions are fully filled.
After filling the Gabion, the lid can be closed. Use the included spirals and attach the lid at every edge including the diaphragm panel. Also twist the ends inwardly for safety reasons.
When superpositioning Gabions, the horizontal connections must be done. This is usually carried out with the help of clips or lacing wire.

submerged arc welding wire |
|
|
Submerged arc welding wire is mostly used for welding of carbon steel and other alloy steel metal that has comparatively low strength. The welding materials are composed with welding wire and flux composite. In the submerged arc welding operation, the composite and property of the welding seams depends on both the welding wire and the flux.
When choosing submerged arc welding wire, the customers should not only consider the effects of flux composition, but also take into account the impact of base metal composition. To achieve the ideal property, one kind of flux (flux melting) and several types of welding wire can be used together. Or, one kind of welding wire with several types of flux complexes. It should be noted that the mechanical properties of the all-weld metal test specimens used for the classification of a wire/flux combination will vary from those obtained in production due to differences in welding procedures such as wire size and welding parameters.

mig welding wire |
|
|
Mig welding wire can be aluminum welding wire, stainless steel welding wire or other alloy wire specially for mig welding processes.
Solid wire MIG welding:
Metal inert gas (MIG) welding was first patented in the USA in 1949 for welding aluminium. The arc and weld pool formed using a bare wire electrode was protected by helium gas, readily available at that time. From about 1952 the process became popular in the UK for welding aluminium using argon as the shielding gas, and for carbon steels using CO 2 . CO 2 and argon-CO 2 mixtures are known as metal active gas (MAG) processes. MIG is an attractive alternative to MMA, offering high deposition rates and high productivity.
Process characteristics
MIG is similar to MMA in that heat for welding is produced by forming an arc between a metal electrode and the workpiece; the electrode melts to form the weld bead. The main differences are that the metal electrode is a small diameter wire fed from a spool and an externally supplied shielding gas is necessary. As the wire is continuously fed, the process is often referred to as semi-automatic welding.
Shielding gas
In addition to general shielding of the arc and the weld pool, the shielding gas performs a number of important functions:
forms the arc plasma
stabilises the arc roots on the material surface
ensures smooth transfer of molten droplets from the wire to the weld pool
Thus, the shielding gas will have a substantial effect on the stability of the arc and metal transfer and the behaviour of the weld pool, in particular, its penetration. General purpose shielding gases for MIG welding are mixtures of argon, oxygen and CO 2 , and special gas mixtures may contain helium. The gases which are normally used for the various materials are:
