In order to install pavers and impact-protective bollards, the level of concrete is set by the height of the paver. The loss of the thin level of paver material to the volume of the concrete surround will only minimally affect the stopping power of the bollard.
Grates act as strainers that stop rubbish, leaves, or dirt from entering the channel. What level of debris filtering is necessary is in part based on likely throughput: a small drain may have a harder time clearing than a larger one.
In the modern era, machining is often a finishing step for products created by forging or casting, to bring forged or cast objects to within precision tolerances
IronArmor matches the strength and durability of iron and steel. Deep color and easy upkeep maintain a beautiful, classical, finished look.
Rated security bollards have been rigorously tested to prove their stopping power. ASTM ratings are assigned to bollards based on the barrier’s ability to stop vehicles of different weights and speeds.
We wondered what the data might show about the changes in bike traffic: how does it compare to changes in vehicle traffic?
There are several factors to consider when choosing trench grate. The contractor might think about aesthetics, cost, wear patterns, total load, weather patterns, and replacement interval.
Is the Southern border really getting a “bollard fence” or a “bollard wall”?
In our Future Cities series, we will look at how engineers and city planners are approaching the challenges and opportunities of our changing world. This week we celebrate innovations in water management in places like Northern BC; Milwaukee, WI; Gresham, OR; and Orange County, CA.
Speed is the primary factor in most vehicle accidents—increasing both risk and severity. As drivers move faster, they have less time to respond to road conditions and any resulting collision causes more damage. To counter the problem of speeding, municipalities can choose from a number of
Foundries are responsible for our current standard of living and industrial development, but most of us know next to nothing about them. So what is a foundry? Foundry Definition In simplified terms, a foundry is a factory where castings are produced by melting metal, pouring
Ductile iron – also referred to as spheroidal or nodular iron – is actually a group of irons that exhibit high strength, flexibility, durability and elasticity due to their unique microstructure. Cast ductile iron normally contains over 3 percent carbon; it can be bent, twisted or deformed without fracturing.
International standards do not translate, metal-for-metal, the way words might translate.
Each type of bollard has its own important, unique purpose.
Is carbon steel better than mild steel? Trick question!
Cast steels can be produced with a wide range of properties. The physical properties of cast steel change significantly depending on chemical composition and heat treatment.
The solvent in wet paint keeps all the other components in suspended liquid form. In contrast, powder coating is applied as a dry powder.
Crash barriers are tested to stop vehicle incursion. Different types of incursion have led to two main testing standards.
Bollards can be chosen to complement the landscape or architecture, adding a sculptural touch.
Lighting can be one of the easiest yet most impactful ways to boost the mood of a landscape.
