Sprung Structures

Pre-Engineered Metal Building

Conventional Construction

Sprung structures are typically delivered 8+ weeks from time of order.

6 plus months

12 plus months

Compact shipping: Sprung structures up to 15,000 square feet. can be shipped in one 40-foot ISO container or on one 48-foot flatbed

6,000 sq.ft. per load

If appropriate soil conditions exist, concrete foundations are not required on Sprung structures up to 160′ wide

Yes – no exceptions

Engineered as an independent/standalone sustainable structure; and can be designed to meet hurricane-force winds and snow loads. Designed on a site specific basis.

Can be designed on a case-by-case basis

Designed and then field constructed

1,00 to 2400 sq.ft. per day, depending on options, complete with finished interior for a Sprung structure

After foundation is in place, a pre-engineered metal building can be constructed at a rate of 2,000 sq. ft. per week.

12-18 months for conventional construction

1-6 months for a Sprung structure

12-18 months for a pre-engineered metal building

18-24 months conventional construction

A Sprung structure has a rust-free structural aluminum framework. Sprung’s patented tensioning system does not require any retensioning of membrane panels for the life of the structure.

A standing seam metal roof is prone to large thermal movements. This causes leaks and requires continuous maintenance, especially at penetrations.

Regular maintenance is required.

Adding additional modules to a Sprung structure is easy

Standard feature: daylight panels in peak of a Sprung structure provide an optimum amount of natural daylight

Significant extra cost

Significant extra cost

Air permeability is almost 0 in a Sprung structure, resulting in superior energy performance.

Poor air-tightness

Moderate air-tightness

Excellent acoustical properties with our comprehensive insulation package and “soft wall” interior membrane

Significant additional costs associated with acoustic treatments needed to make a metal building acceptable for any application where acoustics are a concern (gymnasiums, public assembly, churches, casinos, offices etc.

Limited performance

Indefinite lifespan simply by replacing exterior membrane on a Sprung structure every 20-30 years depending on membrane selection

15-50 depending on quality level

Replace roof every 25+ years
