Revenue from Contract with Customer [Abstract]
Revenue from Contract with Customer	Revenue from Contracts with Customers On January 1, 2018, the Company adopted the New Revenue Standard ("Topic 606") using the modified retrospective method and recorded $0.8 million, net of tax, increase to opening retained earnings on January 1, 2018 as the cumulative effect of adopting Topic 606 for estimated rights of return assets on product sales. Disaggregated revenue In accordance with Topic 606, the Company disaggregates net sales into the following major product groups as noted in Note 12 segment information of these interim financial statements. Wood Construction Products Revenue. Wood construction products represented almost 85% of total net sales in the nine months ended September 30, 2018, refer to Note 12 for products description. Concrete Construction Products Revenue. Concrete construction products represented 15% of total net sales in the nine months ended September 30, 2018, refer to Note 12 for products description. Customer acceptance criteria. Generally, there are no customer acceptance criteria included in the Company's standard sales agreement with customers. When an arrangement with the customer does not meet the criteria to be accounted for as a revenue contract under the standard, the Company recognizes revenue in the amount of nonrefundable consideration received when the Company has transferred control of the goods or services and has stopped transferring (and has no obligation to transfer) additional goods or services. The Company offers certain customers discounts for paying invoices ahead of the due date, which are generally 30 to 60 days. Other revenue. Service sales, representing after-market repair and maintenance, engineering activities and software license sales and services are less than 1.0% of net sales and recognized as the services are completed or the software products and services are delivered. Services may be sold separately or in bundled packages. The typical contract length for service is generally less than one year. For bundled packages, the Company accounts for individual services separately if they are distinct. A distinct service is separately identifiable from other items in the bundled package if a customer can benefit from it on its own or with other resources that are readily available to the customer. The consideration (including any discounts) is allocated between separate services in a bundle based on their stand-alone selling prices. The stand-alone selling prices are determined based on the prices at which the Company separately sells the services. Reconciliation of contract balances Contract assets are the rights to consideration in exchange for goods or services that the Company has transferred to a customer when that right is conditional on something other than the passage of time. Contract liabilities are recorded for any services billed to customers and not yet recognizable if the contract period has commenced or for the amount collected from customers in advance of the contract period commencing. As of January 1, 2018, the Company had no contract assets or contract liabilities from contracts with customers. Other accounting issues Volume discounts. Volume discounts are accounted for as variable consideration because the transaction price is uncertain until the customer completes or fails to purchase the specified volume of purchases (consideration is contingent on a future outcome - occurrence or nonoccurrence). In addition, the Company applies the volume rebate or discount retrospectively, because the final price of each products or services sold depends on the customer's total purchases subject to the rebate program. The estimated rebates are deducted from the transaction price revenues based on the historical experience with the customer. Rights of return and other allowances. Rights of return creates variability in the transaction price. The Company accounts for returned product during the return period as a refund to customer and not a performance obligation. The estimated allowance for returns is based on historical percentage of returns and allowance from prior periods and the customer's historical purchasing pattern. This estimate is deducted from revenues based on the gross transaction price. Principal versus Agent. The Company considered the principal versus agent guidance of the new revenue recognition standard and concluded that the Company is the principal in a third-party transaction. The Company manufactures its products and has control over transfer of its products to Dealer Distributors, Contract Distributors, and end customers. Costs to obtain or fulfill a contract. Costs incurred to obtain a contract are immaterial. Commission cost is not an incremental cost directly related to obtaining a contract. Shipping costs. The Company recognizes shipping and handling activities that occur after the customer has obtained control of goods as a fulfillment cost rather than as an additional promised service. Therefore, the Company recognizes revenue and accrues shipping and handling costs when the control of goods transfers to the customer upon shipment. Advertising costs. Cooperative advertising and partnership discounts are consideration payable to a customer and not a payment in exchange for a distinct product or service at fair value. Estimated cooperative advertising and partnership discounts are reductions to the transaction price. Practical Expedients. The Company did not use either the practical expedient for the existence of a significant financing component or, the practical expedient for expensing certain costs of obtaining a contract.

Revenue from Contracts with Customers

On January 1, 2018, the Company adopted the New Revenue Standard ("Topic 606") using the modified retrospective method and recorded $0.8 million, net of tax, increase to opening retained earnings on January 1, 2018 as the cumulative effect of adopting Topic 606 for estimated rights of return assets on product sales.

The stand-alone selling prices are determined based on the prices at which the Company separately sells the services.

Reconciliation of contract balances

Contract assets are the rights to consideration in exchange for goods or services that the Company has transferred to a customer when that right is conditional on something other than the passage of time. Contract liabilities are recorded for any services billed to customers and not yet recognizable if the contract period has commenced or for the amount collected from customers in advance of the contract period commencing. As of January 1, 2018, the Company had no contract assets or contract liabilities from contracts with customers.

Other accounting issues

Volume discounts. Volume discounts are accounted for as variable consideration because the transaction price is uncertain until the customer completes or fails to purchase the specified volume of purchases (consideration is contingent on a future outcome - occurrence or nonoccurrence). In addition, the Company applies the volume rebate or discount retrospectively, because the final price of each products or services sold depends on the customer's total purchases subject to the rebate program. The estimated rebates are deducted from the transaction price revenues based on the historical experience with the customer.

Rights of return and other allowances. Rights of return creates variability in the transaction price. The Company accounts for returned product during the return period as a refund to customer and not a performance obligation. The estimated allowance for returns is based on historical percentage of returns and allowance from prior periods and the customer's historical purchasing pattern. This estimate is deducted from revenues based on the gross transaction price.

Principal versus Agent. The Company considered the principal versus agent guidance of the new revenue recognition standard and concluded that the Company is the principal in a third-party transaction.
