Ronstan works with winning team in the US Department of Energy Solar Decathlon Competition?
This year the Stevens Institute of Technology team competed against 13 other collegiate teams to win the Solar Decathlon in Irvine, California. The challenge was to build a cost effective and attractive, 1000 square foot solar powered house. Ronstan rods and hardwarewere incorporated into elements of this winning Sure House design.
We spoke with Tom King, the composite fabrication specialist of the SURE House Team, who summarized the winning house design. The SURE House name comes from SUstainable systems plus REsilience. The design incorporates innovative, strong and reliable energy efficient qualities. The house uses a tiny amount of energy, 90% less than a conventional house built to US code. The energy used comes from a well known carbon-free source, the sun.
The sustainability aspect of the design is in the passive house building techniques. The structure is used to create an envelope to reduce energy loss and minimize transfer between the outside world and conditioned space. The exterior is a wood structure made up of engineered lumber beams and joists, 2 x 6 wall framing, a steel deck exoskeleton and an adhered plastic layer for flood proofing. The deck frame was supported by cross bracing with Ronstan stainless steel grade 520 structural rods.
The resilience of the house was vitally important. The team researched and developed a structural system capable of withstanding flood tidal currents up to five feet and 130 MPH hurricane winds. They needed a simple system for sealing the doors and windows to flood water and debris during storms. The solution was found in Ronstan marine industry technology. Glass fiber composite shutters were designed in conjunction with Ronstan and Aquidneck Custom and Gurit.
In the event of a storm, the house is designed to survive on its own. The SURE house can be used a s a prototype for other coastal properties.

Understanding the safety factors of the equipment you are working with is paramount no matter the industry you are working in. With this, it is important to comprehend the differences between working loads, and breaking loads – which may sound the same, but they are not. Any configuration of equipment is only as strong as its weakest, or lowest rated parts. Both terms are a form of rating.
The term working load limit, is most frequently used in rigging terminology, it was the cornerstone of engineering for many years. It is the breaking load of a component divided by an appropriate factor of safety – a safe load that was the maximum carrying capacity. The terms usually apply to equipment such as hooks, slings, shackles and the like.
The working load, sometimes also known as the safety working load, or normal working load (just to confuse things further) is the mass that the equipment being used can safely hold, lift, or lower without there being a fear of breaking. In shorter terms; the maximum load that can be applied to the product safely when in general service. This is most accurate when the product is new and without any ware. This is measured on a straight line pull only, and side pulling can produce different results. It is also important to make sure that all components in a system have the same working load limit.
The breaking load also can be known as the rated capacity. This measure is the force that the piece of equipment breaks when tested at as opposed to measure of mass it can hold. Force is consistently applied at a uniform rate of speed to ascertain the breaking load. The breaking load, or breaking strength as it is also called, is a vital part of the calculation of the working load limit.
The working load is one fifth of the minimum breaking strength. The tests which are undertaken in the laboratory are testing under normal environment type conditions and so when using in adverse weathers or other settings that may include different chemical levels, this should be taken into consideration.
The working load limit of any piece of equipment must never be exceeded, and components must be properly matched. As logic would suggest, it is best to avoid heavy impact shock loads, or any abstract movement such as winging or jerking. Anything like this can lead to stress on the product which leads to the breaking strength and the working load limit being exceeded causing the wider mechanism to fail.
