It secures your shipping container to the ground so it cannot shift, slide, or be moved without authorization. The brackets connect the container to a concrete or asphalt surface, holding it firmly in place. This matters for wind resistance, permitting in some areas, and theft deterrence, since an anchored container is far harder to relocate.

They twist into the container's corner castings, the same heavy steel fittings at each corner used for lifting and connecting, so there is no welding and no drilling into the container itself. The bracket then bolts down to the concrete or asphalt below. Because it uses the existing corner castings, the container stays intact and the brackets can be removed if you need to relocate.

The brackets are made to anchor a container to concrete or asphalt, the firm, solid surfaces that can hold an anchor securely. For the bolts to hold properly you need a suitable slab or paved pad, so a prepared concrete foundation or asphalt surface is ideal. (Confirm the recommended anchor bolts and surface prep from the listing.)

No. Avoiding welding is one of the main advantages, the brackets twist into the corner castings and bolt to the ground, so installation needs anchoring hardware rather than a welder. That makes it a more accessible way to secure a container in place, and it keeps the container unmodified.
