HEB type support arches are structural elements used in mining and tunneling to support and stabilize the surrounding ground. These arches are formed by “H” type hot-rolled steel profiles.
HEB type support arches are installed on the tunnel walls or in the mining gallery, and are fixed to the ground by means of anchors and bolts.

They are arches formed by different sectors of type “H” profile that are joined together by means of union plates and tightening screws, to form the complete arch that will adapt and support the excavated tunnel section.
HEB Type Arch Supports are a popular choice for tunneling and mining due to their strength and durability. They are also easy to install and can be adapted to different sizes and shapes of tunnels and galleries, making it an ideal solution for large diameter sections or the need to support large loads.


HEB Type Arch Supports are commonly used in mining, tunneling and construction projects to provide support and stability to underground structures. Some of the specific application fields include:

Underground mining: HEB support arches are commonly used to provide support and stability in underground mine galleries. These arches can be placed in series to create a complete support system that prevents deformation and collapse of the rock surrounding the gallery.

Tunnel construction: HEB support arches are also used in tunnel construction to provide support and stability to the tunnel walls. These arches can be used together with other support systems, such as anchor bolts and wire mesh, to create a complete and safe support system.

False tunnels and headings: since these arches are a structure in themselves, they are commonly used in tunnel headings and false tunnel construction.

Bridge and building construction: HEB support arches can also be used in the construction of bridges and buildings to provide structural support and stability. These arches can be used to support beams and other structures, and can be designed to support extremely heavy loads.

The use of HEB-type arches in mining, tunneling and construction projects offers several important advantages, including:

Strength: HEB type arches are made of high-strength steel, which allows them to support heavy loads and provide greater stability and safety in structures.

Durability: the steel used in HEB type arches is resistant to corrosion and damage caused by exposure to the elements, allowing them to last for many years without the need for repairs or replacements.

Easy installation: HEB type arches are easy to install and do not require specialized tools or equipment. This makes them ideal for construction and underground mining projects where quick installation and dismantling are required.

Versatility: HEB type arches can be used in a variety of applications, from underground mining to bridge and building construction. Additionally, they can be customized to fit the specific needs of each project.

Cost-effectiveness: HEB type arches are a low-cost solution for providing support and stability in construction and underground mining projects. Additionally, their durability and ease of installation make them a cost-effective long-term investment.
