The main material is one kind of Fiberglass / Glass-firber Reinforced Polyester (FRP / GRP),
with supplementary materials, such as: calcium power, poly-styrene, reinforcing steel bar,etc., the process is compression moulding method, using special steel mould, pressurized by hydraulic pressure machine with heat 180~220 Degree.
So, this material products have more excellence.
More excellence for composite resin material.
1. Against theft: the Regenerated Resin material is no use for 2nd time, thus no recycled if stolen it
2. With good loading capacity, it has strength as steel products, but more tenacity, it will not brake into pieces
3. Long service working life than iron products' 4. Suitable for any temperature 5. The unit weight is more lighter than iron material's at the same size & loading 6. Sealed better between the cover & frame than iron material product's, so, no noise pollution in
using 7. Various color for good decorative effect 8. Good wearable performance, good corrosion resistance, good insulation and never rust.
There're more using area than iron products' Suitable for using in footway, pavements, carriageway, parking area as same as iron products', and more, in corrodent areas such as: chemical factories, in watery area such as: park, garden, even under-water, etc..
Label EN124 Class

Loading Capacity A15, B125,C250,D400, E600,F900
A15, B125 C250, D400 (E600,F900)
Loading Test Mustn�t crack when test. Any crack is meant discard as useless
Allowed crack after test load. The crack is less than 0.2mm after released the pressure.
Current
Various types and used VERY Strong intensity, but easy broken in pieces. Easy producing by casting
Good toughness with strong intensity. Don�t broken in pieces. BUT, Produced by pressure casting mould with heat, the mould cost is more high than iron�s.
Installation Heavy and not easy to install them Large gap between Cover and Frame
Light weight, it�s about 2/3 to 3/4 of the iron cover and frames at same sizes, installing and moving them easily. Small gap between Cover and Frame, not more than 2mm. No noise when cars go through on it.
Endurance Rust easily Anti-Rust cause of the material
Appearance Paint color, and surface paint easily falls off.
Firm color of the body, from surface to core. Don�t losing color. Do not need paint.
Maintenance Normal and possible unlooked for cost cause of rusted or corroded, etc..
Anti-aging and long life-span, against theft cause of composite material.
Performance Damaged by acid, alkali ; rust , electric and heat conduction.
Anti-eroded by acid & alkali, no rust, good insulation of electric & heat.

1. Correct Installation
1.1 The concrete around frame is C20 or over, advised C25.
1.2 The sizes of access hole is NOT more than the clear opening of frame.
1.3 The thickness of support concrete (a) is over 200mm
1.4 The level gap is +/-3mm, between the plane of products and ground. (A-A)
Advised:
CO >= Sizes of Access Hole a >= 200 mm A-A - +/- 3mm
2. Wrong Installation
2.1 CO of frame is small.
2.2 The product is under the level
of ground.
2.2 The product is protruded over
the level of ground.
