The TP Pre-Guard is a temporary protective fence that can absorb impact forces by allowing the fence itself to slide and move during a vehicle collision. The main body features a rigid protective fence structure, and the connection points are designed to allow rotation and extension upon impact from a vehicle, enabling several units to slide and absorb the vehicle's impact force. By allowing movement of the product, it satisfies the performance criteria outlined in the "Installation Standards and Explanations for Protective Fences," while also improving economic efficiency and ease of installation for temporary protective fences.

【NETIS SK-050012-A】 It is possible to widen the road by about 2 meters simultaneously with the construction of conventional block stacking. It is ideal for one-lane roads in mountainous areas, allowing for the installation of vehicle pull-off areas (1.5-lane conversion), sidewalks, bus stops, etc. Additionally, stacking up to four layers allows the internal space of the blocks to be used for nesting and watering areas for wild birds and small animals, making it an environmentally friendly product that coexists with nature.

[NETIS CB-990039-V] This is an egg-shaped pipe type of underground side ditch with a slit drainage function, allowing for continuous water collection. Additionally, its slim shape and lack of a cover make it suitable for narrow roads. It received the Encouragement Award at the 2nd National Land Technology Development Award.

Using the phototropic property that plants inherently possess, which is "buds do not grow downward," we have integrated paving material into the diagonal cut on the product's side, forcing the budding shoots to grow downward, thereby preventing the growth of weeds.

This is an L-shaped retaining wall that complies with the "Precast L-shaped Retaining Wall Design and Construction Manual (Draft) Revised Edition December 2001" (Shikoku Regional Development Bureau, Ministry of Land, Infrastructure, Transport and Tourism). We offer four types: Type 1 (Standard Type), Type 2 (Straight Type), Type 3 (25 cm Cut Type), and Type 4 (50 cm Cut Type).

[NETIS CG-990006-A] By simply installing it on road slopes, it prevents the growth of weeds while maintaining a landscape that harmonizes with the surrounding environment without causing any impact. Additionally, it is effective in fire prevention, such as preventing fires caused by discarded cigarettes.

[NETIS CG-990009-A] This side ditch is a concrete product designed with a slope to allow small animals that have fallen into the drainage channel to return to their natural environment on their own. In areas where various small animals inhabit and where it is difficult to determine installation intervals, continuously installing the overhang type contributes to the preservation of the natural ecosystem. We also offer JIS ditch types and U-shaped ditch types.

[NETIS CG-980014-V] The surface features an art pattern (convex pattern), and the lid support section has a reborn shape (curved shape) with a free gradient side groove. Due to the art pattern, it not only excels in aesthetic appeal but also offers expected anti-slip effects. Additionally, the lid support section's reborn shape (curved shape) is expected to provide noise reduction benefits.

【NETIS CG-980014-V】 Due to the slits, it can continuously collect water in the longitudinal direction. This allows for the collection of road drainage over the shortest distance, preventing water from pooling on top of ditches. Additionally, the artistic pattern enhances the aesthetic aspect. In the case of a retaining wall specification, a cassette wall is used.

【NETIS KK-100053-A】 Due to the slits, it can continuously collect water in the longitudinal direction. This allows for the collection of road drainage over the shortest distance, preventing water from pooling on top of ditches. Additionally, the artistic pattern enhances the aesthetic aspect as well.

【NETIS CB-060014-A】 This is a construction method for installing secondary products such as box culverts, free gradient ditches, and L-shaped retaining walls in mountainous areas and urban areas where large vehicles and heavy machinery cannot enter. It involves installing rails (steel materials) and steel balls, over which products mounted on sleds (steel materials) slide. Manual installation is also possible depending on the weight of the products.

【NETIS HR-110017-A】 This technology aims to "prevent and mitigate traffic accidents" by adding functions that generate "sound" and "micro-vibrations" to gutters to alert pedestrians and drivers of deviating vehicles to potential dangers. If a vehicle deviates toward the sidewalk due to distractions or drowsiness while driving, the generated sound will alert pedestrians to the danger early, while the sound and micro-vibrations will prompt the driver to pay attention, providing high safety for both parties.

[NETIS SK-060003-V] This corresponds to the revision of the standards for "Road Earthworks - Retaining Wall Construction Guidelines" from March 1999. For the foundations of secondary product protective fences, it results in approximately a 70% reduction in construction time compared to site-cast methods. It is also compatible with protective fence foundations from Type A to Type C.

The Reborn gutter reduces noise generation structurally by making the lid receiving part curved. It is available at the same price as standard JIS gutters and adds noise prevention and anti-slip effects. Additionally, it supports internal hanging, significantly improving workability.

The ARVS side ditch - F type is a flexible free gradient side ditch that allows bending to the left and right by approximately 20° each, without the need for mortar filling or cutting of the product, thanks to its curved joint design. In addition to its artistic pattern, it does not produce any on-site cast parts on the surface, resulting in a clean finish that is also aesthetically pleasing. As it does not generate waste materials or dust from product cutting, it is an environmentally friendly road ditch.

The "ECO Nbi Method" is a trench repair method that allows for repairs by replacing only the deteriorated covers with ECO Nbi covers, without damaging the main body of the trench. By securing the primary cover with filling material, it is possible to repair any damaged parts of the trench body simultaneously, allowing for same-day reopening. Additionally, while the primary cover is fixed, the lightweight secondary cover is removable, making maintenance easy even after construction. The construction process does not require chiseling or cutting of the trench body and can be done manually. 【Features】 - Existing trench cover support areas can be utilized as is, even if damaged. - Small-scale construction is possible without heavy machinery, resulting in overall lower costs! - Manual construction is feasible, allowing for speedy execution. - The cover support area is reborn-shaped (curved), significantly reducing noise and vibration! - Utilizing existing trenches minimizes the generation of industrial waste such as concrete debris. - No modifications are made to the existing trench body. - The covers are lightweight and easy to remove, enhancing maintainability. - The absence of unevenness ensures a barrier-free environment, safe for wheelchairs and other mobility aids. 【NETIS Registration Number: HR-120004-A】 *For more details, please download the catalog and contact us.
