The high-strength mortar compact spacer, JL Spacer, has excellent adhesion because it is made of the same material as the main concrete. With a compressive strength of over 70 N/mm², it is ideal for prestressed concrete. Its superior strength and hardness eliminate the need for using two pieces, thereby reducing costs. It does not deform even in high temperatures or sub-zero climates, preventing surface cracking of the concrete. The contact points with the formwork are point contacts, resulting in a clean finish on the concrete surface. For more details, please contact us or refer to the catalog.

The JL-type conical anchor plate was developed with the aim of directly transferring the localized pressure from the jack chair during prestressing to the anchor plate, allowing it to be transmitted to the concrete as an even surface pressure. Based on desk calculations and surface pressure scanner analysis, it is designed to be as economical as possible, resulting in a conical anchor plate that excels in cost reduction and workability. ● For more details, please contact us or download the catalog.

We recommend the use of NS spacers made from the same material to enhance the durability of reinforced concrete structures. NS spacers made from high-strength mortar with a strength of 70 N/mm² or more integrate with the poured concrete structure and prevent the penetration of rainwater, which can cause rust. The clips used for attaching rebar to the NS spacers maintain their function as "spacers that guarantee pure cover," with no metal or organic materials within the cover. NS spacers can be easily attached to rebar, ensuring excellent workability and precise construction. ● For more details, please contact us or download the catalog.
