There are two main types of coil springs – constant rate coil springs and variable rate coil springs.

Body Length: length from coil to coil, not including ends (hooks or loops)
Deflection at Load: the distance a spring compresses or extends when a given load is applied
Free Length (FL): the overall length of a spring in the unloaded position
Initial Tension (IT): the number of pounds of force it will take to overcome the tension holding the spring coils together before the spring will start to extend
Inside Dimension (ID): specified when the spring must fit over a rod or mandrel with enough clearance to operate freely
Load: the force applied to a spring that causes a deflection (i.e., movement)
Max Deflection: the difference between the overall length and maximum extension, measured on one side of spring
Maximum Extended Length: the length of an extension at full rated extension
Outside Dimension (OD):specified when the spring must fit into a circular hole (Work in Hole Diameter) with enough clearance to operate freely or when there areother housing issues)
Pitch: the distance from center to center of the wire in adjacent active coils
Solid Height: height of a compression spring under sufficient load to bring all coils into contact with adjacent coils
Spring Rate (stiffness): the change in load per unit deflection
Stress Relieve: a process that subjects the springs to low-temperature heat treatment to relieve residual stresses
Wire Size (WD): the diameter of the actual spring wire

The spacing of wall ties is crucial for several reasons. First and foremost, it affects the strength and stability of the wall. If the ties are too far apart, the wall may not withstand lateral forces such as wind pressure, leading to structural failure. Conversely, if ties are spaced too closely together, this may lead to increased material costs and unnecessary complications in installation.
