Our heavy duty fiberglass grating is available in both molded and pultruded grating systems. Both are designed to carry forklift and tractor-trailer loads that traditional molded and pultruded FRP grating products are not designed to support. Heavy duty fiberglass grating provides greater durability for higher volume traffic areas as well. Additionally, heavy duty fiberglass grating can be used to free span longer distances than traditional fiberglass grating. For more on heavy duty fiberglass grating, click here.

In recent decades, carbon aerogels have been widely explored by using graphitic carbons and soft carbons, which show advantages in superelasticity. These elastic aerogels usually have delicate microstructures with good fatigue resistance but ultralow strength. Hard carbons show great advantages in mechanical strength and structural stability due to the sp3 C-induced turbostratic “house-of-cards” structure. However, the stiffness and fragility clearly get in the way of achieving superelasticity with hard carbons. Up to now, it is still a challenge to fabricate superelastic hard carbon-based aerogels.
